Electrochemical preparation of anthraquinone and zinc porphyrin coated electrodes: redox activity and film stability

Abstract

This study concerns some aspects of the electrochemical design and characterization of zinc porphyries and anthraquinone-based polymers. The electro-formation of the films on the electrode surface has been achieved by cyclic voltammetry in organic solvents such as dichloromethane and acetonitrile. It is based on the electrochemical oxidative polymerization of the pyrrole or hydroxy-substituted phenyl groups attached to the porphyrin or anthraquinone molecules. The redox characteristics of the polymer films as well as their stability were studied by cyclic voltammetry and spectrophotometry and are compared to those of the starting monomers. The conditions of the electropolymerization of stable and reproducible multicomponent films are also discussed.
