Microporous materials are in high demand because of their ability to adsorb a wide variety of guest molecules. These sorption properties make microporous materials attractive for applications such as storage, separation or catalysis. Optimization of these applications requires a combination of high surface area, tunable functionality, and defined pore structure. Among different classes of microporous materials, coordination polymers have demonstrated a high efficiency for the uptake of several gases and organic molecules. The periodicity of such systems and the ability to modulate the pore size and surface area through modification of either the organic linker or metal cluster have made coordination polymers extremely appealing for sorption and storage applications. Despite the development of microporous materials, such materials to date have relatively low surface areas and pore volumes, with broad pore size distributions.
Researchers at the University of Michigan have developed a organic linkers and coordination polymers derived from these units with enhanced capacity for molecules/ gas and affinity towards a given guest. In particular, linking ligand compound contains three bidentate chemical moieties distributed about a central chemical moiety. Another linking ligand compound includes a bidentate linking ligand and a monodentate chemical moiety. Coordination polymers include a plurality of metal clusters linked together by residues of the linking ligand compounds.
