title: A new thiophene substituted isoindigo based copolymer for high performance ambipolar transistors.
abstract: A novel thiophene substituted isoindigo and its copolymer with benzothiadiazole have been synthesized. The polymer with low lying LUMO energy levels exhibits excellent ambipolar behavior in field effect transistors with both hole and electron mobilities recorded over 0.1 cm(2) V(-1) s(-1).
