A porous and photoactive Ti-MOF based on a novel tetranuclear [Ti2Tb2] cluster.

A robust and porous titanium metal–organic framework (Ti-MOF; LCU-505) has been solvothermally synthesized based on an unprecedented tetranuclear Ti2(μ3-O)2Tb2(μ2-CH3COO)2(H2O)4(OOC−)8 cluster (abbreviated as [Ti2Tb2]) and tritopic 4,4′,4′′-s-triazine-2,4,6-triyl-tribenzoic acid ligand (H3TATB). LCU-505 shows remarkable water stability and permanent porosity for N2 and CO2 gas adsorption. Moreover, LCU-505 demonstrates n-type semiconductor behavior and good photocatalytic activity in the degradation of organic dyes. [ABSTRACT FROM AUTHOR]
