Porous metal-organic hybrid materials, are currently of great interest and importance due to their novel coordination structures, diverse topologies, and potential applications including gas storage, separation, catalysis, and drug delivery. Although catalysis is one of the most important areas in these materials, their catalytic properties have been largely unexplored as compared with recent interest in porous hybrid solids with zeolitic guest-binding properties. The introduction or incorporation of coordinatively unsaturated metal sites (CUS) into porous hybrids is very beneficial since CUS can strongly interact with guest molecules such as gases and organic molecules in adsorption and catalysis. Li et al. have previously presented an example of how CUS can be achieved in the copolymerization of 1,4-benzenedicarboxylate with zinc(II), to give a 3-D metal-organic porous framework. Chui et al. reported that the channel linings of a porous metal coordination polymer HKUST-1 can be chemically functionalized, indicating the potential utilization of unsaturated copper sites. Indeed, it is believed that CUS can offer a promising tool in catalysis because regular arrangements and well-understood surrounding environments of metal centers in the pore channels induce regioselectivity and shape- or size-selectivity towards guest molecules or reaction intermediates. These characteristics are advantageous over other porous materials such as inorganic zeolites and mesoporous materials.
