A π-conjugated charge transfer-type copolymer consisting of an electron-donating thiophene and an electron-accepting 1,3,4-thiadiazole, P(ThdzTh), underwent facile electrochemical p- and n-doping, as revealed by cyclic voltammetry. The copolymer gave a new ambipolar field-effect transistor (FET), which showed typical IDS (source-drain current)-VDS (source-drain voltage) curves in both a p-type working mode and an n-type working mode. In the n-type working mode, the polymer showed a carrier mobility of about 5 × 10-3 cm2 · V-1 · s-1 and an on/off ratio of about 3 × 104.
