Abstract: The substrate binding selectivities of imprinted polymers prepared using bis-methacrylato(4-methyl, 4'-vinyl) 2,2'-bipyridine Cu(II) (1) as the metal-chelating monomer have been investigated. This monomer was designed to minimize the mobility of the metal ions in the binding sites formed by molecular imprinting. A series of bisimidazole derivatives (3-5) were used as the templates for the preparation of imprinted polymers, Formation of monomer:template assemblies in solution was investigated by visible and ESR spectroscopy. Polymerization of these assemblies with ethylene glycol dimethacrylate yielded macroporous, insoluble polymers. In competitive rebinding experiments, the resulting polymers showed greater selectivity for their bisimidazole templates than imprinted polymers prepared previously using an iminodiacetate metal-chelating monomer (2)
