Coordination complexescomprisingmolecular polymerizationoxidation reactionscarboxylate groupsligateCoordination complexes comprising Cu−O clusters havebeen widely used as catalysts in molecular polymerization andoxidation reactions.According to the feature thatcarboxylate groups would ligate with Cu(II) cations underbasic conditions to generate Cu−O cluster structures,42,45,46 theligand 4,4′-disulfo-[1,1′-biphenyl]-2,2′-dicarboxylate acid hastherefore been synthesized, which bears both carboxylate andsulfonate groups. The expectation is that rich coordinatinggroups would allow not only the formation of cluster structuresbut also infinite linkage of such clusters into a polymericframework, which would qualify as a good candidate forheterogeneous catalysis. On the basis of this ligand, and incertain cases together with auxiliary ligands, a series ofcoordination polymers bearing different Cu−O clusterstructures have been synthesized, and their applications incatalyzing oxidation of primary aryl alcohols using hydrogenperoxide as an oxidant upon irradiation of visible light at roomtemperature have thus been examined.
