Abstract
The photoredox and electrochemical behavior of cationic porphyrins immobilized on Nafion was investigated using flash and continuous photolyses and modified electrode techniques. Porphyrin π-radical anions generated by photochemical and electrochemical reduction are stabilized by immobilization on Nafion. In a polymer matrix, the disproportionation of the π-radical anion is inhibited because of lowered mobility of the porphyrin.
