Conducting poly-N-alkylpyrrole polymer films

A series of N-substituted polymer films have been synthesized. The initial characterization of these polymeric films when in the oxidized form indicates that the degree of oxidation of the polymer and the conductivity is reduced with the introduction of N-alkyl substituents. The oxidation potential of the polymer is also changed by the presence of the substituent, whereas polypyrrole oxidizes at -0.2 V, the substituted polypyrrole films with N-alkyl substituents oxidize in the region 0.45-0.64 V. © 1982.
