Conducting Pattern Formation of Electrochemically Polymerized Thiophene in an Organopolysilane Film Imaged by Ultra-Violet Light.
The electrochemical polymerization of thiophene was successfully performed in an organopolysilane film on an indium tin oxide (ITO) glass electrode as patterned by the Ultra-Violet (UV) light irradiation. It was demonstrated that only the UV-exposed polysilane dissolved into polar solvent such as propylene carbonate used as electrolytic solvent and hence electrochemical polymerization proceeded on the ITO electrode masked with the UV-unexposed polysilane. Fine line patterns of 10 μm width were obtained.
