Novel conjugated polymers based on bis-dithieno[3,2-b;2′,3′-d]pyrrole vinylene donor and diketopyrrolopyrrole acceptor: side chain engineering in organic field effect transistors

Abstract

Novel bulky and rigid vinyl-donor–DPP acceptor (D–A) polymers, poly[dithieno[3,2-b:2′,3′-d]pyrrole vinylene dithieno[3,2-b:2′,3′-d]pyrrolediketopyrrolopyrrole] (PB(DTP)V-DPP) were synthesized.
