Abstract Amongst organic semiconducting polymers, polythiophenes are an attractive class due to relatively easy synthesis and good optical and electronic properties. Herein, we report wide-bandgap polythiophene constructed by copolymerization of ester-functionalized bithiophene and thiophene vinylene thiophene monomers. The novel polymer, poly (E)-di(nonadecan-9-yl) 5-(2-(thiophen-2-yl)vinyl)-[2,2':5',2''-terthiophene]-3',4''-dicarboxylate (PDCTVT) exhibited moderate hole mobilities in bottom-gate/top-contact organic field-effect transistors up to 2.18 × 10-2 cm2 V-1 s-1 with higher on-to-off ratio ~105.
