摘要：
A novel push-pull oligomeric semiconductor, ENBT based on naphthodithiophene-benzothiodiazole was successfully designed and synthesized. ENBT was fully characterized by H-1 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 x 10(-2) cm(2)/(Vs) with a current on/off ratio of 10(6)-10(7) after annealed at 160 degrees 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).
