title: Synthesis, characterization and organic field effect transistor performance of a diketopyrrolopyrrole-fluorenone copolymer.
abstract: A diketopyrrolopyrrole (DPP) with fluorenone (FN) based low band gap alternating copolymer (PDPPT-alt-FN) has been synthesized via Suzuki coupling. PDPPT-alt-FN exhibits a deep HOMO level with a lower band gap. Fabricated organic thin film transistors using PDPPT-alt-FN as a channel semiconductor show p-channel behaviour with the highest hole mobility of 0.083 cm(2) V(-1) s(-1) measured in air.
