Polyfuran films have been synthesized by electropolymerization of terfuran and investigated as a function of film preparation conditions in both the doped and undoped state. These films have been characterized by infrared spectroscopy, scanning electron microscopy, optical absorption, X-ray photoelectron spectroscopy, dc conductivity, and electron spin resonance measurements. The electrolyte anion (dopant) used for the preparation of these films heavily influences the π-conjugated system of the polymer backbone. Structural disorder and doping level depends on the nature of the electrolyte anion. CF3SO3 was found to be the best dopant and to cause the least structural disorder or furan ring opening. Electrical conductivities as high as 2 × 10−3 S/cm were obtained in the CF3SO3-doped state. The temperature dependence of the electrical conductivity indicates a thermally activated process with semiconductor-like behavior. The charge transport properties are explained in terms of polaron and bipolaron states. The polymer band gap was measured at 2.35 eV.
