Two novel polyoxometalate (POM)-based metal-organic frameworks (MOFs), [TBA]3[ε-PMo(V)8Mo(VI)4O36(OH)4Zn4][BTB]4/3·xGuest (NENU-500, BTB = benzene tribenzoate, TBA(+) tetrabutylammonium ion) and [TBA]3[ε-PMo(V)8Mo(VI)4O37(OH)3Zn4][BPT] (NENU-501, BPT [1,1'-biphenyl]-3,4',5-tricarboxylate), were isolated. In these compounds, the POM fragments serving as nodes directly connected with organic ligands giving rise to three-dimensional (3D) open frameworks. The two anionic balanced by ions...
Imidazole molecules were frequently incorporated into porous materials to improve their proton conductivity. To investigate how different arrangements of imidazoles in metal–organic frameworks (MOFs) affect the overall conduction, we designed and prepared a MOF-based model system. It includes an Fe–MOF as blank, imidazole@Fe–MOF (Im@Fe–MOF) with physically adsorbed imidazole, imidazole–Fe–MOF (Im–Fe–MOF), which contains chemically coordinated imidazole molecules. The parent Fe–MOF,...
A major goal of metal-organic framework (MOF) research is the expansion pore size and volume. Although many approaches have been attempted to increase MOF materials, it still a challenge construct MOFs with precisely customized apertures for specific applications. Herein, we present new method, namely linker labilization, porosity size, giving rise hierarchical-pore architectures. Microporous robust metal nodes pro-labile linkers were initially synthesized. The mesopores subsequently created...
A unique strategy, sequential linker installation (SLI), has been developed to construct multivariate MOFs with functional groups precisely positioned. PCN-700, a Zr-MOF eight-connected Zr6O4(OH)8(H2O)4 clusters, judiciously designed; the Zr6 clusters in this MOF are arranged such fashion that, by replacement of terminal OH(-)/H2O ligands, subsequent insertion linear dicarboxylate linkers is achieved. We demonstrate that distinct lengths and functionalities can be sequentially installed into...
Precise placement of multiple functional groups in a highly ordered metal-organic framework (MOF) platform allows the tailoring pore environment, which is required for advanced applications. To realize this, we present comprehensive study on linker installation method, stable MOF with coordinatively unsaturated Zr6 clusters was employed and linkers bearing different were postsynthetically installed. A Zr-MOF inherent missing sites, namely, PCN-700, initially constructed under kinetic...
A novel zeolite-like metal–organic framework (ZMOF) with sodalite topology, [Zn(HL)]·DMA (IFMC-1, L = 4,5-di(1H-tetrazol-5-yl)-2H-1,2,3-triazole and IFMC Institute of Functional Material Chemistry), was solvothermally synthesized based on an N-rich aromatic ligand without a NH2 group. It exhibits high CO2 uptake selective CO2/N2 adsorption capacity. For the first time, we investigated influence large number uncoordinated nitrogen atoms from rings for in ZMOFs. This result reveals that...
Abstract A 2D, extremely stable, metal–organic framework (MOF), NENU‐503 , was successfully constructed. It displays highly selective and recyclable properties in detection of nitroaromatic explosives as a fluorescent sensor. This is the first MOF that can distinguish between molecules with different numbers NO 2 groups.
Guided by thermodynamics, we have synthesized two mixed-linker zirconium-based metal–organic frameworks (Zr-MOFs), namely, PCN-133 and PCN-134. Both of them possess a layer-pillar structure, in which the connection between Zr6 clusters primary BTB linkers form (3,6)-connected kdg layer that is further extended into 3D auxiliary DCDPS/TCPP (BTB = benzene tribenzoate, DCDPS 4,4′-dicarboxydiphenyl sulfone, TCPP tetrakis(4-carboxyphenyl)porphyrin). PCN-134 demonstrates high porosity (N2 uptake...
We successfully assembled the photocatalytic titanium-oxo cluster and photosensitizing porphyrinic linker into a metal-organic framework (MOF), namely PCN-22. A preformed carboxylate is adopted as starting material to judiciously control MOF growth process afford single crystals. This synthetic method useful obtain highly crystalline titanium MOFs, which has been daunting challenge in this field. Moreover, PCN-22 demonstrated permanent porosity activities toward alcohol oxidation.
Metal–organic frameworks (MOFs) based on Ti-oxo clusters (Ti-MOFs) represent a naturally self-assembled superlattice of TiO2 nanoparticles separated by designable organic linkers as antenna chromophores, epitomizing promising platform for solar energy conversion. However, despite the vast, diverse, and well-developed Ti-cluster chemistry, only scarce number Ti-MOFs have been documented. The synthetic conditions most Ti-based are incompatible with those required MOF crystallization, which has...
Flexible metal-organic frameworks (MOFs) are highly desirable in host-guest chemistry owing to their almost unlimited structural/functional diversities and stimuli-responsive pore architectures. Herein, we designed a flexible Zr-MOF system, namely PCN-700 series, for the realization of switchable catalysis cycloaddition reactions CO2 with epoxides. Their breathing behaviors were studied by successive single-crystal X-ray diffraction analyses. The amplitudes series modulated through...
A stable porous carbazole-based luminescent metal–organic framework, NENU-522, was successfully constructed. It is extremely in air and acidic/basic aqueous solutions, which provides the strategy for material encapsulation of Ln3+ ions with tunable luminescence application light emission. More importantly, Ln3+@NENU-522 can emit white by encapsulating different molar ratios Eu3+ Tb3+ ions. Additionally, Tb3+@NENU-522 found to be useful as a fluorescent indicator qualitative quantitative...
Crystal engineering of metal-organic frameworks (MOFs) has allowed the construction complex structures at atomic precision, but yet to reach same level sophistication as organic synthesis. The synthesis MOFs with multiple and/or inorganic components is ultimately limited by lack control over framework assembly in one-pot reactions. Herein, we demonstrate that multi-component unprecedented complexity can be constructed a predictable and stepwise manner under simple kinetic guidance, which...
Mixed-linker strategy is a promising way to construct multifunctional metal–organic frameworks (MOFs). In this review, we demonstrate the recent developments, discussions and challenges related preparation applications of four types mixed-linker MOF materials.
Abstract Cooperative cluster metalation and ligand migration were performed on a Zr‐MOF, leading to the isolation of unique bimetallic MOFs based decanuclear Zr 6 M 4 (M=Ni, Co) clusters. The 2+ reacts with μ 3 ‐OH terminal H 2 O ligands an 8‐connected [Zr (OH) 8 (H O) ] form cluster. Along cluster, is observed in which Zr–carboxylate bond dissociates M–carboxylate bond. Single‐crystal single‐crystal transformation realized so that snapshots for cooperative processes are captured by...
Metal halide perovskite quantum dots, with high light-absorption coefficients and tunable electronic properties, have been widely studied as optoelectronic materials, but their applications in photocatalysis are hindered by insufficient stability because of the oxidation agglomeration under light, heat, atmospheric conditions. To address this challenge, herein, we encapsulated CsPbBr3 nanocrystals into a stable iron-based metal–organic framework (MOF) mesoporous cages (∼5.5 4.2 nm) via...
Ligands with flexible conformations add to the structural diversity of metal–organic frameworks but, at same time, pose a challenge design and prediction. Representative examples include Zr-tetracarboxylate-based MOFs, which afford assorted structures for wide range applications, but also complicate control. Herein, we systematically studied formation mechanism series (4,8)-connected MOFs by altering substituents on different positions organic linkers. Different ligand rotamers give rise...
The incorporation of large π-conjugated ligands into metal–organic frameworks (MOFs) can introduce intriguing photophysical and electrochemical properties the framework. However, these effects are often hindered by strong π–π interaction low solubility arylated ligands. Herein, we report synthesis a porous zirconium-based MOF, Zr6(μ3-O)4(μ3-OH)4(OH)6(H2O)6(HCHC) (PCN-136, HCHC = hexakis(4-carboxyphenyl)hexabenzocoronene), which is composed hexacarboxylate linker with hexabenzocoronene...
2D metal-organic frameworks (2D-MOFs) have recently emerged as promising materials for gas separations, sensing, conduction, and catalysis. However, the stability of these 2D-MOF catalysts tunability over catalytic environments are limited. Herein, it is demonstrated that 2D-MOFs can act stable highly accessible catalyst supports by introducing more firmly anchored photosensitizers bridging ligands. An ultrathin MOF nanosheet-based material, Zr-BTB (BTB = 1,3,5-tris(4-carboxyphenyl)benzene),...
