A highly porous NbO type metal-organic framework constructed from an expanded tetracarboxylate

A novel NbO type microporous metal-organic framework Cu2L (ZJU-32; H4L = 5'-((3,5-dicarboxyphenyl)ethynyl)-[1,1':3',1 ''-terphenyl]-4,4 ''-dicarboxylic acid) constructed from an elaborately designed tetratopic ligand was solvothermally synthesized and structurally characterized. The activated ZJU-32a exhibits high permanent porosity with the Brunauer-Emmett-Teller (BET) surface area of 3831 m(2) g(-1) and the pore volume of 1.482 cm(3) g(-1), enabling it to be a promising material for both methane storage and carbon dioxide capture at room temperature.
