title: Supramolecular assemblies obtained by large counteranion incorporation in a well-oriented polycationic copolymer.
abstract: The anodic oxidation of a two bipyridiniums meso-substituted octaethylporphyrin leads to the coating of the working electrode by a cationic polymeric film. Description of the formation and morphological properties of this conducting film are presented along with the electrochemical synthesis of the initial porphyrinic subunit used as monomer for the electropolymerization. We investigated the effects of the counteranion on the morphology of the copolymer 2-poly-Zn where the initial regular arrangement of swollen coils aggregated in the form of "peanuts" all oriented in the same direction was strongly modified in the gain of a new still well oriented supramolecular structure.
