title: Effect of selenophene in a DPP copolymer incorporating a vinyl group for high-performance organic field-effect transistors.
abstract: A new polymeric semiconductor, PDPPDTSE, is reported which is composed of a diketopyrrolopyrrole moiety and selenophenylene vinylene selenophene, with a high field-effect mobility achieved through intermolecular donor-acceptor interactions. The field-effect mobility of OFET devices based on PDPPDTSE by spin-casting is 4.97 cm(2)  V(-1)  s(-1) , which is higher than predecessor polymeric semiconductors.
