Porous structures in which pore size and functionality could be varied systematically have been designed by changing the functional groups of ligands. Highly porous metal coordination polymers [Cu3(MBTC)2(H2O)3]n (where MBTC is methyl-1,3,5-benzenetricarboxylate) and [Cu3(EBTC)2(H2O)3]n (where EBTC is ethyl-1,3,5-benzenetricarboxylate) have been solvothermally synthesized in mixed solvents of water and ethanol. They both have two different [Cu2(O2CR)4] units (where R is an aromatic ring), which create the same three-dimensional framework with open metal sites and high surface area. The pore size and adsorption properties are altered by introduction of the organic groups -CH3 or -C2H5. Both of them exhibit relative low adsorption of water due to the hydrophobic functional groups. CuMBTC showed high adsorption of CO2 and CH4 at low pressure.
