Abstract: | The macromolecular bound protoporphyrin IX and its metal complexes, poly-(protoporphyrin-co-acrylamide), cobalt(II) poly(protoporphyrin-co-acrylamide)], zinc-(II)poly(protoporphyrin-co-acrylamide)], and manganese(III) poly(protoporphyrin-co-acrylamide)] chloride were synthesized. The absorption and emission spectra have been obtained for the macromolecular porphyrins. The lifetime of the excited singlet state of the protoporphyrin IX was found to decrease from 13.7 to 6.2 ns after polymerization. The cyclic voltammograms of polymeric protoporphyrin coated electrodes have been obtained. © 1992 John Wiley & Sons, Inc. |
