Fabrication and photoelectric conversion of densely packed C60–ethylenediamine adduct microparticle films-modified electrode covered with electrochemically deposited polythiophene thin-films

Abstract

Polythiophene-modified densely packed C60–ethylenediamine adduct microparticle films were prepared using a combination of liquid–liquid interfacial precipitation of the adduct microparticles and electrochemical polymerization of 2,2′-bithiophene. The amount of polythiophene was varied as a function of scanning cycles of the applied potential during electrochemical polymerization. Fluorescence-emission properties of these composite films suggested the role of C60–ethylenediamine adduct microparticle film as a photosensitizer in addition to an electron acceptor for polythiophene. Furthermore, cathodic photocurrents were generated via excitation of C60–ethylenediamine adduct microparticle film and polythiophenes using the half-photocell properties of the electrode modified with composite film in the presence of methylviologen.
