Copper(II) complexes have been shown to be competent oxidation catalysts in biological systems such as galactose oxidase, as well as in model complexes. Small model complexes with pyridine and amide nitrogen donors have shown some promise in mimicking the function of galactose oxidase and offer a number of peripheral sites for tuning and derivatization. Our research is directed toward the development of a copper(II)-based oxidation catalyst that can be incorporated into a porous metal-organic framework (pMOF). These pMOF catalysts would offer the advantages of some metal- and/or ligand-based tunability of the system while providing a heterogeneous catalyst to facilitate product recovery and cleanup. Current efforts utilize a pyridine-2,6-bisamide tridentate ligand.. This tri-dentate ligand system leaves 1-2 open coordination sites for substrate binding and offers the advantage of being readily alterable by changing amine used in the ligand synthesis, a requirement for development of future pMOFs.
