Notes:
The copolymer which has both ligand sites (4-vinylpyridine) and redox sites (N-(p-vinylbenzyl)-3-carbamoyl-1,4-dihydropyridine) was synthesized by the dithionite reduction of the copoly(4-vinylpyridine-N-(p-vinylbenzyl)-3-carbamoylpyridinium chloride) and the reduction of a central ferric-iron of ferriprotoporphyrin IX by the above-described copolymer was studied spectrophotometrically in dimethyl sulfoxide. The rate of the reduction by the copolymer was much faster than by N-benzyl-3-carbamoyl-1,4-dihydropyridine. This acceleration by the copolymer could be explained by the intramolecular reduction of ferriprotoporphyrin IX which was coordinated by the pyridine residue of the copolymer.
