Popis:	A new copolymer of benzo[1,2-b:4,5-b′]dithiophene and 3,3′-bis(tridecanoxy)-5,5′-bithiophene was synthesized through Stille copolymerization. The bis-(3-alkoxythiophene) monomer was synthesized through a silver fluoride mediated, palladium-catalyzed cross-coupling, in which bromide functional groups were preserved instead of consumed. The copolymer has been characterized and applied in field-effect transistors, giving a hole mobility of 2 × 10−3 cm2/Vs and an on/off ratio >106, with negligible hysteresis, on standard silicon substrates. © 2010 Wiley Periodicals, Inc.
