Abstract

A novel push-pull oligomeric semiconductor, ENBT based on naphthodithiophene-benzothiodiazole was successfully designed and synthesized. ENBT was fully characterized by ¹H NMR, MS, thermogravimetric analysis (TGA), UV–vis spectra, and cyclic voltammetry (CV). Furthermore, ENBT-based OFETs were fabricated by solution-processed dip-coating technique and its charge transporting property was investigated. The film of ENBT exhibited a hole mobility as high as 1.4 × 10⁻² cm²/(Vs) with a current on/off ratio of 10⁶–10⁷ after annealed at 160 °C. In order to give an insight to the transporting property of ENBT films, thin film morphologies after annealing at different temperatures were also studied by atomic force microscopy (AFM).
