Abstract

Fullerene-poly(ethylene dioxythiophene) (polyEDOT) composite films consisting of 3,4-ethyeledioxythiophene (EDOT) and a thiophene derivative of C60 fullerene (ThC60) or C60 fullerene were fabricated on a transparent indium-tin-oxide (ITO) electrode by electrochemical polymerization of the electrolyte solution of ThC60 (or C 60) and EDOT. Incorporation of the C60 fullerene moiety in the polythiophene film was strongly suggested from absorption spectra of the composite film. We have found a higher degree of incorporation of the C 60 fullerene moiety into the ThC60-polyEDOT film, as compared with the C60-polyEDOT film. In the presence of methylviologen as an electron acceptor, the as-prepared C60-polyEDOT and ThC60-polyEDOT composite films generated stable cathodic photocurrents in the 400-700nm region with broad peaks. The photocurrent intensity and the internal photon-to-current quantum efficiency of the ThC 60-polyEDOT composite film were considerably larger than those of C60-polyEDOT and polyEDOT films. The thiophene unit of ThC 60 was confirmed to be quite effective for a stable incorporation of the C60 fullerene moiety in the film and a higher photocurrent generation.
