Abstract

Graphical abstract: Highlights: A novel push-pull semiconductor, namelyENBT was designed and synthesized. The mobility properties ofENBT film were evaluated. The morphology property ofENBT films were investigated by AFM. Abstract: A novel push-pull oligomeric semiconductor, ENBT based on naphthodithiophene-benzothiodiazole was successfully designed and synthesized.ENBT was fully characterized by 1 H 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 ofENBT exhibited a hole mobility as high as 1.4 × 10 −2 cm 2 /(Vs) with a current on/off ratio of 10 6 –10 7 after annealed at 160 °C. In order to give an insight to the transporting property ofENBT films, thin film morphologies after annealing at different temperatures were also studied by atomic force microscopy (AFM).
