Abstract
Stable tunable channels are formed by pillared-layer-type coordination networks [{Cu2(pzdc)2(L)}n] (pzdc = pyrazine-2,3-dicarboxylate; L = pyrazine, 4,4′-bipyridine, N-(4-pyridyl)isonicotinamide). Not only their channel sizes, shapes, and chemical environments are systematically built up by tuning the pillar ligands, but also the porosity is maintained in the absence of the included guest molecules. These compounds can adsorb methane, and the amount of gas adsorption is controllable by the type of pillar ligands.
