Abstract
Reaction of poly(γ-ethyl L-glutamate) with N-(3-aminopropyl)imidazole gives an imidazole doped polymer which forms 6-coordinate complexes with iron(III) porphyrins. Modified electrodes are prepared using these porphyrin containing polymers. The new materials are characterised by cyclic voltammetry, UV-visible spectroscopy and by surface enhanced resonance Raman spectroscopy. The techniques allow complete characteization of the oxidation state and ligation state of the iron centre. The modified electrodes will catalyse the reduction of dioxygen.
