Electron transfer in a novel synthetic membrane analogue for cytochrome c
Abstract
Ester groups in poly(γ-ethyl L-glutamate) were converted to the amide with 1-(3-aminopropyl)imidazole; coordination of deuteroporphyrin-IX-FeIIICl dimethyl ester to the imidazole groups gave a novel electroactive polymer with reversible redox activity in aqueous NaClO4[E°=–0.43 V vs. sodium chloride saturated calomel electrode (SSCE)] and in aqueous NaCl (E°=–0.30 V vs. SSCE).
