Characterization of microporous copper(II) dicarboxylates (fumarate, terephthalate, and trans-1,4-cyclohexanedicarboxylate) by gas adsorption

Some microporous coordination polymers have been synthesized from copper salts and dicarboxylic acids. These stuctures were characterized by gas adsorption methods. The methane adsorption capacities of these coordination polymers were measured under high pressure. The measurement disclosed that these coordination polymers had uniform micropores and methane adsorption capacities almost the same as that of zeolite 5A.
