Metal–organic framework (MOF) thin films are important in the application of sensors and devices. However, the application of MOF thin films in organic field effect transistors (OFETs) is still a challenge to date. Here, we first use the MOF thin film prepared by a liquid-phase epitaxial (LPE) approach (also called SURMOFs) to modify the SiO2 dielectric layer in the OFETs. After the semiconductive polymer of PTB7-Th (poly[4,8-bis(5-(2-ethylhexyl)thiophene-2-yl)benzo[1,2-b:4,5-b′]dithiophene-co-3-fluorothieno[3,4-b]thiophene-2-carboxylate]) was coated on MOF/SiO2 and two electrodes on the semiconducting film were deposited sequentially, MOF-based OFETs were fabricated successfully. By controlling the LPE cycles of SURMOF HKUST-1 (also named Cu3(BTC)2, BTC = 1,3,5-benzenetricarboxylate), the performance of the HKUST-1/SiO2-based OFETs showed high charge mobility and low threshold voltage. This first report on the application of MOF thin film in OFETs will offer an effective approach for designing a new kind of materials for the OFET application.Keywords: dielectric layer; epitaxial growth; metal−organic frameworks; organic field-effect transistor; thin film;

AbstractArrays of ultrasmall and uniform carbon nanodots (CDs) are of pronounced interest for applications in optical devices. Herein, we describe a low-temperature calcination approach with rather inexpensive reactants. After glucose molecules had been loaded into the pores of metal–organic frameworks (MOFs), well-defined CD arrays were produced by heating to 200 °C. The size and spacing of the CDs could be controlled by the choice of templating MOF: HKUST-1, ZIF-8, or MIL-101. The sizes of the obtained CDs were approximately 1.5, 2.0, and 3.2 nm, which are close to the corresponding MOF pores sizes. The CD arrays exhibited interesting photophysical properties, including photoluminescence with tunable emission and pronounced nonlinear optical (NLO) effects. The NLO properties of the obtained CD arrays were significantly different from those of a CD suspension, thus indicating the existence of collective phenomena.

•A cluster precursor-based methodology for TiO2 fabrication is established.•The thermolysis process towards TiO2 samples was affected by the cluster precursors.•The H2 production rates of TiO2 can be improved by selecting ligands on precursors.Titanium-oxo clusters (TOCs) are important model complexes and potential precise single-source precursors of TiO2 materials. We report here a series of TiO2 samples derived from TOCs with the same wheel-like Ti8O8 clustercore but different stabilizing ligands. Our results demonstrate that the ligands on TOCs not only influence the phase-transition during themolysis, but more importantly tune the photocatalytic H2 evolution activities of the obtained TiO2 materials. Through 500 °C calcination, the nanosized Ti8O8 cluster stabilized by organic benzoate ligands gives rise to a TiO2 sample with H2 production rate of 611 μmol/h/g. When the stabilizing ligands are changed to inorganic SO42−, a significant improvement of H2 evolution activity has been achieved, resulting in a 7-times higher value of 4527 μmol/h/g.

A palladium catalyst (Pd-Cs) encapsulated metalloporphyrin network PIZA-1 thin film with bifunctional properties has been developed through a modified epitaxial layer-by-layer encapsulation approach. Combining the oxidation activity of Pd-Cs and the acetalization activity of the Lewis acidic sites in the PIZA-1 thin film, this bifunctional catalyst of the Pd-Cs@PIZA-1 thin film exhibits a good catalytic activity in a one-pot tandem oxidation–acetalization reaction. Furthermore, the surface components can be controlled by ending the top layer with different precursors in the thin film preparation procedures. The catalytic performances of these thin films with different surface composites were studied under the same conditions, which showed different reaction conversions. The result revealed that the surface component can influence the catalytic performance of the thin films. This epitaxial encapsulation offers a good understanding of the tandem catalysis for thin film materials and provides useful guidance to develop new thin film materials with catalytic properties.

Metal–organic frameworks (MOFs) containing rich transition metal ions and functional ligands have attracted interest for the non-noble metal oxygen evolution reaction (OER). However, the realization of MOF-based thin films for optimizing and improving electrocatalysis remains a significant challenge. In this work, we report a homodispersed CeO2 encapsulated cobalt–porphyrin network derived thin film by epitaxial encapsulation approach for optimizing and improving OER performance. The OER activity can be optimized effectively via tuning the thicknesses and calcination temperatures of the cobalt–porphyrin network PIZA-1 thin film. After loading a Ce(III) coordination compound into PIZA-1 by the epitaxial encapsulation method and calcination at 400 °C, a thin film of PIZA-1 derivative with homo-dispersed CeO2 was obtained successfully for greatly improved electrocatalytic OER performance (an overpotential of 370 mV at 10.0 mA cm−2). The work presented here will be extended to the fabrication of other composite thin film electrode materials for high electrocatalytic performance.

FIR-34 is an 8-fold interpenetrating dia framework constructed from small dinuclear [Mn2(COO)4] secondary building units (SBUs), while FIR-35 based on large Mn5 SBUs is a non-interpenetrating framework with (3,8)-connected tfz-d network. Both of them have low porosity. However, the other non-interpenetrating framework (FIR-36) with large mesopores is built by rod-shaped Mn(II)-carboxylate SBUs. Gas sorption measurements for FIR-36 give a Langmuir surface area of 825.3 m2·g–1 and a H2 uptake of 134.5 cm3·g–1 at 77 K and 1 bar.

This critical review presents the various synthetic approaches and chiral chemistry of metal–camphorate frameworks (MCamFs), which are homochiral metal–organic frameworks (MOFs) constructed from a camphorate ligand. The interest in this unique subset of homochiral MOFs is derived from the many interesting chiral features for both materials and life sciences, such as asymmetrical synthesis or crystallization, homochiral structural design, chiral induction, absolute helical control and ligand handedness. Additionally, we discuss the potential applications of homochiral MCamFs. This review will be of interest to researchers attempting to design other homochiral MOFs and those engaged in the extension of MOFs for applications such as chiral recognition, enantiomer separation, asymmetric catalysis, nonlinear sensors and devices.

•The charge distribution strategy on the synthesis of boron imidazolate frameworks.•Functional boron imidazolate frameworks with diverse topologies based on 3- and 4-connected boron imidazolate ligands.•The mechanical and catalytic properties of boron imidazolate frameworks.Boron imidazolate frameworks (BIFs) are a family of metal–organic frameworks (MOFs) that based on the cross-linking of predetermined boron-imidazolate complexes by metal cations. One fundamental feature of BIFs is that both three-connected tripodal liangds and four-connected tetrahedral ligands can be readily synthesized prior to solvothermal synthesis. In this review, we focus on the recent advances in BIFs that possess zeotype and other types of topological nets based on the three- or four- connected boron imidazolate ligands. In particular, we emphasize the basic design principles of the synthetic methodology to construct specifically topological BIFs, especially, towards the zeolitic topologies.

We present the formation of the largest titanium–oxo cluster, [Ti42(μ3-O)60(OiPr)42(OH)12)]6–, with the first fullerene-like Ti–O shell structure. The {Ti42O60} core of this compound exemplifies the same icosahedral (Ih) symmetry as C60, the highest possible symmetry for molecules. According to the coordination environments, the Ti centers in this cluster can be arranged into a Platonic {Ti12} icosahedron and an Archimedean {Ti30} icosidodecahedron. The solution stability of this cluster was confirmed by electrospray ionization mass spectrometry. The spherical body of the {Ti42O60} core has an inside diameter of 1.05 nm and an outside diameter of 1.53 nm, which could be directly visualized by high-resolution transmission electron microscopy. Our results demonstrate that titanium oxide can also form fullerene-like shell structures.

We report a 3.6 nm Ti52–oxo cluster with precise atomic structure, which presents a largest size record in the family of titanium–oxo clusters (TOCs). The crystal growth of such large Ti52 is based on a stepwise interlayer assembly approach from Ti6 substructures. The possible growth mechanism of Ti52 could be deduced from crystal structures of two substructures, Ti6 and Ti17, which were also synthesized under similar conditions as Ti52. Moreover, these TOCs show cluster-size-dependent photocatalytic hydrogen evolution activities with Ti52 giving a H2 production rate up to 398 μmol/h/g, which is also the highest record in the family of TOCs. This work not only represents a milestone in constructing large TOCs with comparable sizes as TiO2 nanoparticles but also brings significant advances in improving photocatalytic behaviors of TOCs.

Reported here is a versatile method capable of generating pore space partition in zeolitic boron imidazolate frameworks (BIFs), which is based on the coexistence of presynthesized boron imidazolate complexes and charge balancing carboxylate ligands. Using this method, boron imidazolate complexes are used to form zeolitic nets, while the carboxylate serves to partition large channel spaces into multiple domains. The generality of this method is shown by two distinct boron imidazolate frameworks mimicking GIS (BIF-41) and ABW (BIF-42) zeotype topologies. BIF-41 shows high selectivity sorption of CO2 over N2.

Chirality is one of the essential features in our living life and exerts a wide variety of applications in enantio-adsorption/separation. However, the mechanism between chirality and enantio-adsorption/separation is very significant in homochiral porous materials; in particular, the understanding of the relationship between crystalline orientations and chiral behavior is a challenging but important mechanism. In this work, homochiral porous crystalline metal organic framework (MOF) materials were grown on hydroxyl- and carboxyl-functionalized substrates, resulting in homochiral porous thin films with different orientations. The enantioselectivity and adsorption rates in two different oriented homochiral porous thin films were studied by using gas-phase quartz crystal microbalance (QCM) experiment of chiral probe molecules. The different mass uptake and time constant showed that the chiral behavior can be obviously influenced by the crystalline orientations on the same homochiral porous thin films. This study will not only offer a good model to understand the mechanism of chiral behavior in homochiral porous materials but also provide guidance for developing new homochiral-oriented porous thin films with high enantioselectivity or enantioseparation.Keywords: chiral chemistry; homochiral porous material; metal−organic framework; orientation dependence; thin film

Organic–inorganic hybrid lead organohalide perovskites are inexpensive materials for high-efficiency photovoltaic solar cells, optical properties, and superior electrical conductivity. However, the fabrication of their quantum dots (QDs) with uniform ultrasmall particles is still a challenge. Here we use oriented microporous metal–organic framework (MOF) thin film prepared by liquid phase epitaxy approach as a template for CH3NH3PbI2X (X = Cl, Br, and I) perovskite QDs fabrication. By introducing the PbI2 and CH3NH3X (MAX) precursors into MOF HKUST-1 (Cu3(BTC)2, BTC = 1,3,5-benzene tricarboxylate) thin film in a stepwise approach, the resulting perovskite MAPbI2X (X = Cl, Br, and I) QDs with uniform diameters of 1.5–2 nm match the pore size of HKUST-1. Furthermore, the photoluminescent properties and stability in the moist air of the perovskite QDs loaded HKUST-1 thin film were studied. This confined fabrication strategy demonstrates that the perovskite QDs loaded MOF thin film will be insensitive to air exposure and offers a novel means of confining the uniform size of the similar perovskite QDs according to the oriented porous MOF materials.Keywords: confined fabrication; luminescent; perovskite; porous thin film; quantum dots

Four isostructural pillared-layer metal–organic frameworks (as 1-ims series) are successfully synthesized via the charge-balance approach, where trigonal [Zn2(CO2)3] cluster-based cationic layers [Zn2(NH2–BTB)]+ (NH2–H3BTB = 1,3,5-(3-benzoic acid) aniline) are connected by a series of 2-substituted imidazolates. The 1-ims supply a systematic platform to explore the adsorption of light hydrocarbons. Especially, 1-ims shows good adsorption selectivity of C3/C1 and C2/C1, and the selectivities of C3H8/CH4 are all over 100 at room temperature. These results demonstrate that introduction of functional group plays a key role on tuning the channel and pore size as well as improving the adsorption selectivity.

A functional Cu(I) boron imidazolate framework (BIF) with a ladder-chain structure can not only change to another single-chain structure by incorporating 4,4′-bipyridine, but can also act as a reducing agent to load trimetal Au–Ag–Pd nanoparticles directly; the BIF with loaded noble NPs showed an excellent reduction effect on 4-nitrophenol. Moreover, we obtained a porous borocarbonitride by the direct carbonisation of this low-dimensional BIF. The resulting porous borocarbonitride exhibits fast adsorption behavior for 4-nitrophenol and can be a high-temperature conductor.

We describe the fabrication of hybrid yet well-ordered porous nanoparticle (NP) arrays with full three-dimensional periodicity by embedding nanometer-sized metal–organic clusters (MOCs) into metal–organic frameworks (MOFs). Although conventional NP@MOF encapsulation procedures failed for these fairly large (1.66 nm diameter) NPs, we achieved maximum loading efficiency (one NP per pore) by using a modified liquid phase epitaxy (LPE) layer-by-layer approach to grow and load the MOF. The preformed NPs, homochiral Ti4(OH)4(R/S-BINOL)6 clusters (Ti-MOC, BINOL = 1,1′-bi-2-naphthol), formed a regular lattice inside the pores of an achiral HKUST-1 (or Cu3(BTC)2, BTC = 1,3,5-benzenetricarboxylate) MOF thin film. Exposure to the different enantiomers of methyl lactate revealed that the NP@MOF metacrystal is quite efficient regarding enantiomer recognition and separation. The approach presented here is also suited for other MOF types and expected to provide a substantial stimulus for the fabrication of metacrystals, crystalline solids made from nanoparticles instead of atoms.Keywords: homochirality; metacrystals; metal−organic framework; nanocluster;

The framework of FIR-53 contains 1D channels along the c axis with a cross section of 18 × 13 Å2. FIR-54 also consists of large channels with the 10.5 × 10.5 Å2 open windows. These porous materials efficiently trap Cr2O72– inorganic pollutant ions via the single-crystal-to-single-crystal (SC-SC) approach. The Cr2O72– uptake capacities of FIR-53 and FIR-54 are high to 74.2 and 103 mg/g, respectively. Furthermore, the Cr2O72– trapping–releasing process of FIR-53 displays good regeneration. Meaningfully, the structure of FIR-53 after ion exchange can be accurately obtained by single-crystal X-ray diffraction, which further elaborates the SC-SC transformation.

As a new family of hybrid inorganic–organic materials with large porosity, metal–organic frameworks (MOFs) have received attractive attention recently on encapsulating functional guest species. Although the encapsulation of luminescent guest into bulk MOFs can tune the luminescent property, the powder composite materials are limited to the application in optical sensors and devices. In the present work, we use a modified liquid-phase epitaxial (LPE) pump method for the fabrication of lanthanide coordination compounds (LCCs)-encapsulated MOF thin film on substrate with high encapsulation efficiency. The resultant composite film reveals an oriented and homogeneous composite film, in which a white light emission by tuning the LCCs of red, blue and green emission can be obtained. This strategy may open new perspectives for developing high-encapsulation-efficiency, oriented, and homogeneous solid-state lighting composite films in the application of optical sensors and devices.Keywords: encapsulation; lanthanide coordination compounds; liquid phase epitaxy; MOF thin film; tunable white-light emission

A series of 3D neutral boron imidazolate frameworks (BIFs) with octahedral metal centers were synthesized based on the charge-balancing principle. Au–Pd nanoparticles (NPs) with a mean size of 2.12 nm were then successfully obtained and encapsulated in these BIF structures through the simultaneous reduction of Au3+/Pd3+ ions by B–H bonds of tridentate boron ligands. The very small sizes of these Au–Pd NPs are attributed to the pore confinement effect of BIFs. This work not only brings new methodology for the construction of neutral BIFs but also suggests a new strategy for loading smaller-sized bimetallic NPs into BIFs.

The self-assembly of metal boron imidazolate cages is successfully realized. The cage-based materials display good properties on gas adsorption and reducing noble metals.

Abstract
Homochiral metal–organic frameworks (HMOFs) are efficient materials for enantioselective adsorption. However, the combination of size selectivity and enantioselectivity is still a major challenge in the field of HMOFs. Herein, two enantiomorphic HMOFs built from predesigned proline-derived ligands are presented. Both of them show multiple homochiral features: they contain four different helical chains and three types of helical channels. Due to the size effect of the helical channels, each HMOF can enantioselectively adsorb methyl lactate with high ee. The results reveal a new approach toward size-dependent enantioselective separation of racemic compounds by using HMOFs built from inexpensive proline derivatives.

Abstract
A three-dimensional metal–organic framework (MOF) was synthesized by combining 4-pyrazolecarboxylic acid and adenine. This MOF exhibits reversible flexibility and breathing adsorption behaviors in response to light hydrocarbons, with high capacity. The flexibility of the structural transitions was studied on the molecular scale by obtaining the crystal structures at 303, 353 and 373 K. The bridging nitrogen atoms of the pyrazolate rings act as a “kneecap” around the M⋅⋅⋅M axis, which causes the rotation of ligands around the M⋅⋅⋅M axis in response to external stimulus, thus giving rise to the deformation of the framework structure.

Presented here is a new direct patterning method, printer-type lithography technology, for the formation of lanthanide coordination compounds (LCCs) single crystal in different spatial locations. We first integrate this technology in digital controlled emission by patterned deposition of LCCs. We demonstrate its usefulness in the control of emission intensity by regulating print cycles, so that the emission intensity can be digitally controlled. This printer technology can also be used to precisely control the location at which a single LCC crystal is grown, which provides great promise in the application of anticounterfeiting barcode. Besides, by varying the stoichiometric ratio of the lanthanide ions in the identical cartridge, a fluent change of emission colors from white, orange, pink, to blue green was achieved. Therefore, this low-cost and high-throughput patterning technique can be readily applied to a wide range of areas including micro-/nanofabrication, optics, and electronics studies.Keywords: controlled emission; lanthanide coordination compounds; luminescent emission; patterned deposition; spatial location

A cobalt imidazolate (im) framework material [Co(im)2]n was employed to use as a trimethylamine (TMA) gas sensor and the [Co(im)2]n sensor can be easily fabricated by using Ag–Pd interdigitated electrodes. Gas sensing measurement indicated that the [Co(im)2]n sensor shows excellent selectivity, high gas response and a low detection limit level of 2 ppm to TMA at 75 °C. The good selectivity and high response to TMA of the sensor based on [Co(im)2]n may be attributed to the weak interaction between the TMA molecules and the [Co(im)2]n framework. That may provide an ideal candidate for detecting freshness of fish and seafood.Keywords: cobalt imidazolate framework; gas sensor; selectivity; trimethylamine

A series of zinc(II) compounds, [Zn2(btca)2(im)2]·(DMA) (1; H2btca = benzotriazole-5-carboxylate acid, im = imidazole, and DMA = N,N-dimethylacetamide), [Zn(btca)(im)]·(DMF) (2; DMF = N,N-dimethylformamide), [Zn2(btca)2(tmdpy)]·2(DMF)·5(H2O) [3; tmdpy = 1,3-di(4-pyridyl)propane], and [H2N(CH3)2]2[Zn3(btca)4]·(DMF) (4), have been successfully synthesized via rational control of experimental conditions. Single-crystal X-ray diffraction analyses indicate that compounds 1 and 2 are isomers, and both of them exhibit two-dimensional structures with the same uninodal 3-connected fes topology. Additionally, the three-dimensional (3D) structure of 3 was obtained by using tmdpy instead of an im ligand under synthesis conditions similar to those of compound 2. Interestingly, compound 3 presents a pillared-layer structure with a (3,4)-connected (4.82.103)(4.82) topology. When 4,4′-bipyridine was used to replace tmdpy, the assembly between Zn2+ ions and H2btca ligands produced a chiral 3D framework of 4. Furthermore, compound 4 showed a new (3,4)-connected topology with a vertex symbol of (4.6.84)2(4.6.8)(4.82)(6.82)2(6.85). A comparison of all compounds suggested that the structural diversity of the compounds could be tuned by altering the auxiliary ligand. In addition, the photoluminescent properties of compounds 1–4 were measured.

Presented here are three imidazole-linked tetrahedral zinc phosphonate frameworks based on a special ligand 2-(1-imidazole)-1-hydroxyl-1,1′-ethylidenediphosphonic acid (= ImhedpH4) with both an organic imidazole linker and inorganic phosphonate groups. Three new compounds, namely, [Zn2(ImhedpH2)2(ox)](H2ppz) (1), Zn3(ImhedpH)2(H2O)4 (2) and [Zn3(Imhedp)2](H2ppz) (3) (ox = oxalate and ppz = piperazine), were obtained by hydrothermal synthesis and structurally characterized by single-crystal X-ray diffraction. Compound 1 shows a chain structure with the ox ligands linking the [Zn2(ImhedpH2)2] units, and the resulting chains are further connected to form a 3D structure through the strong N–H⋯O and O–H⋯O hydrogen bonds between the neighboring chains. Compound 2 displays an inorganic layer structure with dangling imidazole units, where these protonated imidazoles also act as pillars between adjacent inorganic layers. Compound 3 features an unusual chiral three-dimensional (3D) Zn-Imhedp framework with guest H2ppz2+ cations. It can be topologically represented as a 4-connected qtz network. Furthermore, the luminescent properties of the three compounds were investigated in the solid state.

Abstract
A novel three-dimensional metal–organic framework with primitive cubic (pcu) topology exhibits interesting tunable photoluminescent emission based on the variation of excitation light at room temperature. By judicious choice of two different conjugated organic linkers incorporating in a certain framework, the contributions of distinct emission bands may be finely controlled. This work may provide a new route to explore functional luminescent materials with tunable photoluminescence.

By controlling the pH value of the reaction system, two sets of lanthanide (Ln)–tris((4-carboxyl)phenylduryl)amine (Ln = Ce, Pr, Nd, Sm) frameworks have been generated. Four isostructural noninterpenetrating frameworks (FIR-8 to FIR-11) are constructed from rod-shaped secondary building units and four other isostructural frameworks (FIR-12 to FIR-15) based on single Ln nodes are described as 8-fold interpenetrating dia-type nets. Gas sorption measurements for FIR-8 give a Langmuir surface area of 633.8 m2·g–1 and a H2 uptake of 165.2 cm3·g–1 at 77 K and 1 atm. However, FIR-12 with smaller pores can hardly adsorb any N2 and H2. Because both FIR-8 and FIR-12 crystallize in acentric space group, the second-harmonic generation (SHG) measurements indicate that both of them display strong powder SHG efficiencies, which are approximately 8 and 3 times as strong as that of a potassium dihydrogen phosphate powder. In addition, the fluorescent emissions of all compounds in the solid state are also investigated in detail.

Two novel 1D copper-bridged tetrahedral polyoxometalate nanoclusters with tetrameric rare-earth cores and germanotungstate vertexes, Na3H7[Cu(en)2]5[Cu(en)2(H2O)]2[RE4Ge4W46O164(H2O)3]·nH2O (RE = GdIII, n = 25 for 1; RE = YIII, n = 23 for 2; en = ethylenediamine), have been hydrothermally synthesized and structurally characterized by elemental analyses, IR spectra, thermogravimetric analysis (TGA), and single-crystal X-ray diffraction. The most prominent structural feature of 1 and 2 consists of unprecedented tetrahedral RE-substituted germanotungstate nanoclusters {[(α-GeW11O39RE)2(μ3-WO4)(α-GeW11O39RE(H2O))](μ4-WO4)[α-GeW11O39RE(H2O)2]}24–, in which four mono-REIII-substituted Keggin [α-GeW11O39RE(H2O)n]5– (n = 0, 1, 2) moieties are combined together with the aid of two WO42– connectors. What’s more interesting is that adjacent tetrahedral nanoclusters are interconnected with each other via [Cu(en)2]2+ bridges, forming a 1D extended chain architecture. To our knowledge, 1 and 2 are the first polyoxometalate-based Cu–RE containing 1D chain constructed from tetrahedral RE-substituted germanotungstate nanoclusters and copper–organic bridges. Furthermore, the solid-state electrochemical and electrocatalytic properties of 1 and 2 have been carried out in 0.5 mol·L–1 Na2SO4 + H2SO4 aqueous solution by entrapping them in a carbon paste electrode. 1 and 2 display apparent electrocatalytic activities for the nitrite and bromate reduction.

To investigate the role of solvents on the self-assembly of coordination frameworks, the reactions between MnCl2·4H2O and thiophenedicarboxylate (thb) ligand in different solvents at 120 °C produced four new Mn–thb complexes. These Mn–thb frameworks all use a rod-and-spacer assembly mode, but their rod-packing architectures are totally different because of the structure-directing effect of solvents. The topologies of 1, 2, 3 and 4 are novel (3,5)-connected net, hex, irl and sra, respectively. The results reveal that solvents with different conformations play a significant role in promoting the diversity of structures. In addition, the magnetic properties of 1, 2 and 3 have also been studied.

Remarkably, this stable microporous framework exhibits high CO2 and H2 uptake and good selectivity for CO2 over N2 at 273 K. Its sorption capacity for some hydrocarbons is also investigated.

As a newly developed synthetic method, urothermal synthesis was employed to construct a series of photoluminescent lanthanide–organic frameworks based on a flexible ligand. Eight new lanthanide compounds, namely Ln2(obb)3(e-urea)(H2O) [Ln = Er (1), Yb (2), Ho (3); obb = 4,4′-oxybisbenzoic acid, e-urea = ethyleneurea], Ln2(obb)3(e-urea)(H2O)3 [Ln = Tb (4), Dy (5), Eu (6)], La2(obb)3(H2O)1.5(e-urea) (7) and [Sm2(obb)3(H2O)5]·(H2O) (8), have been synthesized under urothermal reactions and structurally characterized by single-crystal X-ray diffraction. Compounds 1, 2 and 3 are isostructural and possess three-dimensional structures with (3,3,4,5,5)-connected new topology, while compounds 4, 5 and 6 are almost identical in structure with the space group P21/n and display an unusual (4,4,5)-connected topology. Compound 7 is a unique two-dimensional structure with the centrosymmetric space group Pbca and possesses a (4,4,7,7)-connected new topology. Different from the above-mentioned seven frameworks (1–7), compound 8 features a three-dimensional framework with unprecedented (3,4,4,5,6)-connected new topology. In these compounds, the structural variations were rationalized by the effect of lanthanide contraction, the effect of e-urea as the structure-directing agent and the different coordination modes of the flexible obb ligand. The luminescent properties of compounds 4 and 6 have been studied in the solid state at room temperature, and both of them display metal-based luminescence.

Five new Cd(II) coordination polymers based on mixed 5-position substituted 1,3-benzenedicarboxylate ligands (R=NO2/OH/CH3) and 1,4-bis(imidazol-1-yl)benzene (L1)or 1,4-bis(1-imidazol-yl) -2,5- dimethyl benzene (L2), namely [Cd(5-NO2-ip)(L1)·H2O] (1), [Cd(5-OH-ip)(L1)]n (2), [Cd(5-NO2-ip) (L1)0.5(H2O)2]n (3), {[Cd(5-NO2-ip)(L2)0.5(H2O)]·H2O} (4), [Cd(5-CH3-ip)(L2)(H2O)2]n (5), have been synthesized hydrothermally and structurally characterized. With different substituted groups in the organic ligands, five compounds exhibit five distinct framework structures. By changing the pH value, compound 1 with 2-fold interpenetrating (4,4)-layer structure and compound 3 with three-dimensional diamond-type framework are obtained, respectively, from the assembly of Cd(NO3)2·4H2O, 5-NO2-ip and L1 ligand. The replacement of 5-NO2-ip with 5-OH-ip leads to a compound 2 which features a doubly pillared layered structure with pcu topology. Compounds 4 and 5 are constructed from L2 ligand with 5-NO2-ip or 5-CH3-ip, respectively. Compound 4 has non-interpenetrating (4,4) layer, while compound 5 shows unusual 2D->3D polycatenation of bilayers. The results reveal a new approach toward tuning structural topologies of coordination polymers through modifying the substitute groups in organic ligands. Furthermore, the photoluminescent properties of compounds 1–5 have been studied in the solid state at room temperature.Graphical abstractWith different substituted groups in the organic ligands, five compounds exhibit five distinct framework structures.

Abstract
Three new metal-organic frameworks (MOFs) were prepared by solvo(hydro)thermolysis and further characterized as framework isomers. The structural transformation from non-porous to porous MOFs and the purity of these products can be modulated by controlling the reaction temperature. The periodic-increased porosity observed was further confirmed by CO2 adsorption isotherms. Owing to the presence of acylamide groups in the pore walls and the flexible nature of the skeleton of these MOFs, highly selective CO2 adsorption over N2 was observed, as well as structure-dependent periodic varieties in luminescence properties.

From a basic tetrahedral Cu4I4 cluster, a new MTN-type cluster–organic framework (COZ-1) containing giant 64512 and 512 cages was successfully constructed. The 64512 cage has an inner diameter of 2.6 nm and a large pore volume of 9.2 nm3; these tetrahedral Cu4I4 clusters with bulky size offer new opportunities for not only the formation of 4-connected zeotype structures but also the integration of porosity and photoluminescent properties from both the cluster and the framework.

To explore the catalytic activity of heterometallic cluster-organic frameworks, three 3d-3d heterometallic cluster-organic frameworks based on the cooperative assembly of tetrahedral Cu4I4 and metal-carboxylate clusters with potential open metal sites were synthesized and described in detail. The structure of 1 consists of tetrahedral [Cu4I4(INA)4]4– metalloligands (INA = isonicotinate) linking unusual Zn8(μ4-O)(COO)12(H2O)4 clusters into a (4,12)-connected network. Compound 2 features a 2-fold interpenetrating 4-connected bbf-type framework based on new [Cu4I4(INA)2(DBO)2]2– metalloligands (DBO = 1,4-diazabicyclo[2.2.2]octane) and paddle-wheel Zn2(COO)4 units. The 2-fold interpenetrating diamond-type framework 3 is constructed from tetrahedral [Cu4I4(INA)4]4– metalloligand and Mn2(COO)4(H2O)2(DMF) unit with potential open Mn centers. All three framework materials have notable catalytic activity on the diethylzinc addition to aromatic aldehydes, and the catalytic properties of compound 1 have been studied in detail. The results reveal that the heterogeneous catalysis of the diethylzinc addition to aromatic aldehydes by using cluster-organic framework as catalyst is determined by several experimental factors, such as temperature, reaction time, and the incorporation of electron-withdrawing groups in aromatic aldehydes.Keywords: additional reaction; catalysis; cluster; crystal structure; metal−organic framework;

Presented here is the unusual guest selectivity observed in the self-assembly process of a porous tetrahedral imidazolate framework material [Zn(ad)(int)] (TIF-1, ad = adeninate, int = isonictinate). Four distinct solvent molecules, such as N,N-dimethylformamide (DMF), ethyleneurea (e-urea), N-methy1-2-pyrrolidone (NMP) and N,N-dimethylacetamide (DMA), can be trapped in the same in situ generated TIF-1 framework, respectively, which are identified by single-crystal X-ray diffraction. Complicated mixed solvent systems are investigated to understand the guest selectivity of TIF-1. The results reveal TIF-1 has strict guest selectivity following the sequence DMF > e-urea > NMP > DMA. Moreover, the activated TIF-1 after methanol-exchange exhibits high H2 and CO2 adsorption capacity and remarkable selectivity of CO2 over N2.

Compounds 1–7 are anionic frameworks with 8-connected bcu topology, while compound 8 features a neutral 6-connected rob-type framework with guest e-urea molecules. In these structures, lanthanide ions show dicapped trigonal prism, pentagonal bipyramid, and tricapped trigonal prism coordination configurations, respectively, and the TDC ligands exhibit different coordination modes. Versatile helical substructures are presented in these compounds. The photoluminescent properties of compounds 3 (Eu) and 8 (Nd) were studied. Moreover, compound 8 can perform single-crystal-to-single-crystal guest exchange. The ethanol-exchange mechanism of 8 can be ascribed to the kinetically controlled flexibility (KCF).

High stability and permanent porosity are the premise of general applicability for metal–organic framework materials (MOFs). By varying degrees of success on increasing the connectivity of the linear pillar 4,4′-bipyridine (bpy), two isostructural flexible frameworks [M2(obb)2(DMF)2]·2DMF (1, M = Zn or Cu; H2obb = 4,4′-oxybis(benzoic acid), DMF = N,N-dimethylformamide) with no gas sorption are structurally modified into two rigid frameworks [Zn2(obb)2(bpy)]·DMF (2) and [Cu2(obb)2(bpy)0.5(DMF)]·2DMF (3) with notable gas sorption and separation properties. Especially for 3, it exhibits gas selective uptake for the adsorption of CO2 over N2 and CH4 under 273 K and has an interesting physically lock effect in benzene and cyclohexane sorption. The results provide a successful strategy on tuning framework stability of flexible structures via adding rigid pillars.

This paper presents a comparative study on the tuning of structural topologies using three isomers of biphenyldicarboxylates as bridging ligands. Compound 1 based on 2,4′-bpdc features a three-dimensional (3D) framework with 6-connected mab topology. Compound 2 based on 3,4′-bpdc is another 3D framework, but it possesses a rare 3-fold interpenetrating 4,6-connected fsh net, while compound 3 based on linear 4,4′-bpdc shows unusual 2D → 3D parallel polycatenation of (4,4) layers. Furthermore, the luminescent properties of three compounds are investigated in the solid state.

Four identical MBBs are observed in four structures with diverse topological nets. The obtained compound 1 only contains individual MBBs, while compounds 2–4 have the combination of two kinds of MBBs. Remarkably, the structure of 1 with trimeric [Zn3(OH)(CO2)5] MBBs exhibit interesting nanotubes. In particular, the choice of solvent in each synthesis is important for the network diversity of the Zn–1,3,5-benzenetricarboxylate frameworks reported here.

Zeolite A (LTA) is of much interest in zeolite family because of its large-scale industrial applications. Making Zeolite A (a typical 4-connected tetrahedral framework material) with a lower connectivity (3-connected) might lead to new open architecture with expanded ring size and enhanced functionality. The first interrupted Zeolite A with 3-connected network has been experimentally realized here by a boron imidazolate (im) framework material (BIF-20) with 3-coordinate BH(mim)3– building units. Additionally, a new strategy toward the construction of functional microporous metal–organic frameworks with interrupted zeolite-type topologies is presented by both 3-connected boron imidazolate frameworks (BIF-20 and BIF-21). BIF-20 has an unusual tetrahedral framework with both debonded α and β cages, and exhibits high H2 uptake capacity.

The three-dimensional framework shows one-dimensional open channels that accommodate the coordinated and guest DMF molecules. Gas adsorption measurements on compound 4 indicate that the desolvated solid of 4 adsorbs CO2 and shows nonporous behavior toward N2. The adsorption favoring CO2 over N2 may arise from the chemical environments of the host framework, which contains the polar –OH groups of the phenyl and the π-electrons of the ligands. Magnetic measurements on compound 4 indicate that there is an antiferromagnetic interaction between Gd3+ ions.

Reported here are two three-dimensional CuI cluster-based organic frameworks, (Cu4I4)2(Cu6I6)(DABCO)6 (1) and (Cu4I3)2(CN)2(DABCO)3 (2) (DABCO = 1,4-diazabicyclo[2.2.2]octane) constructed from mixed CuI clusters and mixed linear ligands, respectively. Compound 1 displays an unprecedented 4-connected network based on Cu4I4 and Cu6I6 clusters, respectively, as tetrahedral and pseudosquare planar 4-connected nodes, while 2 displays a novel 5-connected BN-type network composed of 5-connected cationic Cu4I3+ clusters linked by mixed cyanide anion CN− and DABCO ligands. The CN− in 2 derives from the solvent CH3CN and adopts a rare μ4-bridging mode. 1 shows chiral symmetry and photoluminescence at 298 K. The mixed strategies prove to be a useful fool to enrich the synthetic chemistry and structural diversity of cluster organic frameworks.

This critical review presents the various synthetic approaches and chiral chemistry of metal–camphorate frameworks (MCamFs), which are homochiral metal–organic frameworks (MOFs) constructed from a camphorate ligand. The interest in this unique subset of homochiral MOFs is derived from the many interesting chiral features for both materials and life sciences, such as asymmetrical synthesis or crystallization, homochiral structural design, chiral induction, absolute helical control and ligand handedness. Additionally, we discuss the potential applications of homochiral MCamFs. This review will be of interest to researchers attempting to design other homochiral MOFs and those engaged in the extension of MOFs for applications such as chiral recognition, enantiomer separation, asymmetric catalysis, nonlinear sensors and devices.

Reported here is a versatile method capable of generating pore space partition in zeolitic boron imidazolate frameworks (BIFs), which is based on the coexistence of presynthesized boron imidazolate complexes and charge balancing carboxylate ligands. Using this method, boron imidazolate complexes are used to form zeolitic nets, while the carboxylate serves to partition large channel spaces into multiple domains. The generality of this method is shown by two distinct boron imidazolate frameworks mimicking GIS (BIF-41) and ABW (BIF-42) zeotype topologies. BIF-41 shows high selectivity sorption of CO2 over N2.

By employing the nanosized tris((4-carboxyl)phenylduryl)amine ligand to assemble with Ln3+ ions, a series of 2-fold interpenetrating lanthanide–organic frameworks (LnOFs; Ln = Y, Eu–Yb; FIR-16 to FIR-24) and heterometallic EuxTby–LnOFs (x + y = 2; FIR-25 to FIR-27) possessing the novel (3,6)-connected topology have been generated. FIR-17 with a high surface area of 941 m2 g−1 is an interesting flexible framework. Reversible fluorescence switching upon the presence or removal of guest molecules with different sizes is observed by using FIR-17 as a promising solvent sensor. This work presents an outstanding integration of photoluminescent properties and porosity for flexible lanthanide–organic frameworks.

Presented here is the unusual guest selectivity observed in the self-assembly process of a porous tetrahedral imidazolate framework material [Zn(ad)(int)] (TIF-1, ad = adeninate, int = isonictinate). Four distinct solvent molecules, such as N,N-dimethylformamide (DMF), ethyleneurea (e-urea), N-methy1-2-pyrrolidone (NMP) and N,N-dimethylacetamide (DMA), can be trapped in the same in situ generated TIF-1 framework, respectively, which are identified by single-crystal X-ray diffraction. Complicated mixed solvent systems are investigated to understand the guest selectivity of TIF-1. The results reveal TIF-1 has strict guest selectivity following the sequence DMF > e-urea > NMP > DMA. Moreover, the activated TIF-1 after methanol-exchange exhibits high H2 and CO2 adsorption capacity and remarkable selectivity of CO2 over N2.

A pair of 3-D homochiral metal–organic frameworks (HMOFs) based on a mixed semi-rigid 5-(2-carboxypyrrolidine-1-carbonyl)isophthalate (PIA) ligand and rigid 4,4′-bipyridine (bipy), [Co3((R)-PIA)2(bipy)3]·6H2O (1-D) and [Co3((S)-PIA)2(bipy)3]·6H2O (1-L) are synthesized and structurally characterized. They are enantiomers and exhibit three-dimensional open frameworks. In each structure, the PIA ligands link the Co centers into homochiral frameworks with large open channels that are occupied by the bipy ligands. Interesting helical chains built from the connectivity between PIA ligands and Co centers are presented. Antiferromagnetic coupling is observed in 1-D. These results demonstrated that the mixed ligand approach is successful for the construction of HMOFs.

Three tetrahedral tetrazolate frameworks with two different 4-connected topologies including lonsdaleite (lon, for 1) and diamond (dia, for 2 and 3) have been synthesized, and the lon-type framework with high CO2 and H2 uptake capacity can irreversibly transform to the dia-type framework via solvent-exchange.
