Synthesis and electrochemical response of poly-(1-aminoanthracene) films
The electrooxidation of 1-aminoanthracene on platinum electrodes was investigated in acetonitrile using different supporting electrolytes by cycling the electrode potential in different potential ranges. The addition of pyridine to the electrolytic solution results in an increase in the current density leading to an enhancement in the growth rate of the polymeric film. Electrogravimetric measurements were performed in order to determine the polymerization efficiency. No defined structure was observed in the newly grown film, however a fiber-like structure was defined after several voltammetric cycles in aqueous solution. The film was characterized by infrared spectroscopy, and the films prepared under different conditions presented a well-defined electrochemical response. The electrochemical response can be characterized by a redox couple the shape of which depends on the electrolyte used in the polymer synthesis. Marked differences in the response and charge density can be observed in the voltammetric curves for the different polymers.
