Abstract

Electropolymerization of 9,9-dialkylfluorenes (Rnfluo, n: number of carbons in the chain) with long normal alkyl chains (n = 4, 5, 6, 8, and 10 compared with n = 1) were investigated during sequential potential cycling. Among the Rnfluos, significant film growths were observed for the Rnfluo with n = 1, 8, and 10. The R8fluo and R 10fluo-based films were also found to consist of the monomer unit with higher molecular weight than the R1fluo-based film. A doping/undoping response of the new electroactive poly(R10fluo) film was compared with that of poly(R8fluo) from a fundamental viewpoint as an electrochemical capacitor material.
