Polymer semiconductor PDPPF-DFT , which combines furan-substituted diketopyrrolopyrrole (DPP) and a 3,4-difluorothiophene base, has been designed and synthesized. PDPPF-DFT polymer semiconductor thin film processed from nonchlorinated hexane is used as an active layer in thin-film transistors. As a result, balanced hole and electron mobilities of 0.26 and 0.12 cm 2 /(V s) are achieved for PDPPF-DFT . This is the first report of using nonchlorinated hexane solvent for fabricating high-performance ambipolar thin-film transistor devices.
