Redox-active films of ferrocene covalently attached to polypyrrole

Abstract

Thin films of an electroactive polymer may be obtained from the anodic electropolymerisation of an N-substituted ferrocenylpyrrole. Direct electropolymerisation yields a film which exhibits rectifying behaviour but whose electroactivity decays. Co-polymerisation with N-methylpyrrole gives a film with a stable Fc–Fc⁺ response.
