Abstract

The first tetracene diimide derivative fused with four thiophene rings, TT-TDI, was synthesized by an FeCl(3) mediated oxidative cyclodehydrogenation reaction. TT-TDI exhibited a low band gap of 1.52 eV and amphoteric redox behavior. TT-TDI also showed a liquid crystalline property and ambipolar charge transport in thin film field-effect transistors.
