Abstract:
Poly(pyrrole-pyromellitimide) films were prepared by the anodic oxidation of N,N’-bis[2-(lpyrrolyl)ethyl]pyromellitimide (BEP) in acetonitrile media. These films showed a stable redox behavior in acetonitrile as well as in water media containing 0.1 M tetraalkylammonium salt or LiClO4, as the supporting electrolyte. Poly(BEP) adsorbed a layer of poly(Ne-4-nitrobenzoyl-L-lysine) and this bilayer exhibited charging of both electroactive groups.
