Porous Bimetallic Ti-MOFs for Photocatalytic Oxidation of Amines in Air.

A family of microporous titanium-containing metal-organic frameworks (denoted as MTi-CPCDC, M = Mn, Co, Ni) has been synthesized by using a bimetallic [MTi(μ-O)(COO)] cluster and a tritopic carbazole-based organic ligand HCPCDC. MTi-CPCDC are stable and display permanent porosity for N and CO uptake, ranking among the most porous titanium-based metal-organic frameworks. MTi-CPCDC crystals exhibit n-type semiconductor behavior.

A porous and photoactive Ti-MOF based on a novel tetranuclear [TiTb] cluster.

A robust and porous titanium metal-organic framework (Ti-MOF; LCU-505) has been solvothermally synthesized based on an unprecedented tetranuclear Ti(μ-O)Tb(μ-CHCOO)(HO)(OOC) cluster (abbreviated as [TiTb]) and tritopic 4,4',4''--triazine-2,4,6-triyl-tribenzoic acid ligand (HTATB). LCU-505 shows remarkable water stability and permanent porosity for N and CO gas adsorption. Moreover, LCU-505 demonstrates n-type semiconductor behavior and good photocatalytic activity in the degradation of organic dyes.

Mesoporous MOF Based on a Hexagonal Bipyramid Co-Cluster: High Catalytic Efficiency on the Cycloaddition Reaction of CO with Bulky Epoxides.

A mesoporous cobalt-based metal-organic framework (LCU-606) was synthesized based on a hexagonal bipyramid Co(μ-O) cluster and an ,,','-tetrakis-(4-benzoic acid)-1,4-phenylenediamine ligand (HTBAP). LCU-606 featuring large pore diameters of 21.7 Å and exposed Lewis-acid metal sites could serve as an excellent heterogeneous catalyst for CO cycloaddition reaction with various epoxide substrates under mild conditions (1 atm CO, 60 °C, and solvent free).

A robust and porous titanium metal-organic framework for gas adsorption, CO capture and conversion.

A robust and porous titanium metal-organic framework (Ti-MOF; LCU-402) has been hydrothermally synthesized through combining a tetranuclear TiCa(μ-O)(μ-HO)(HO)(OC-) cluster and a tritopic 1,3,5-benzene(tris)benzoic (BTB) ligand. LCU-402 shows remarkable stability and permanent porosity for CO, CH, CH, CH, and CH gas adsorption. Moreover, LCU-402 as a heterogeneous catalyst can smoothly convert CO under a simulated flue atmosphere into organic carbonate molecules by cycloaddition reactions of CO and epoxides, indicating that LCU-402 might be a promising catalyst candidate in practical applications.

Robust acid-base Ln-MOFs: searching for efficient catalysts in cycloaddition of CO with epoxides and cascade deacetalization-Knoevenagel reactions.

A family of microporous and robust Ln(iii)-based metal-organic frameworks (1-Ln, Ln = Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb) have been obtained using 4,4',4''-nitrilotribenzoic acid (HNTB) in NMP-HCl solvent. Both single-crystal and powder X-ray diffraction analyses demonstrate that 1-Ln are isostructural and possess 3D frameworks with permanent porosity for Ar and CO adsorption. Strikingly, the incorporation of both Lewis acidic lanthanide ions and the basic triphenylamine group into 1-Ln makes them efficient acid-base catalysts for both cycloaddition of epoxides with CO and one-pot cascade deacetalization-Knoevenagel reactions.
