Anodic polymerization of dithienosilole and electroluminescent properties of the resulting polymer

Anodic oxidation of 2,6-bis(trimethylsilyl)-4,4-di(p-tolyl)dithienosilole gave a dark orange solid polymer with a small band gap. The spectral data of the polymer indicated that polymerization had proceeded with retention of silole rings in the polymer, although decomposition of the dithienosilole ring system had competed to an extent. Applications of the spin-coated polymer films as the electroluminescent device materials are described.
