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

Polythiophene-modified densely packed C-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 C-ethylenediamine adduct microparticle film as a photosensitizer in addition to an electron acceptor for polythiophene.
