Organic field-effect transistors(OFETs) based on organic semiconducting polymers have received much attention as promising devices for use in future soft electronics industries. Important progress has recently been achieved in OFET performance through the development of high mobility organic semiconductors. In particular, the use of the donor–acceptor(D–A) alternating design yields semiconducting polymers with outstanding charge carrier mobilities that are enabled by the resulting strong intramolecular D–A interactions. A series of D–A type polymers with long, branched alkyl side chains was synthesized with various donor. This study provides insight into the structure–property relationships in D–A copolymers based on long-donor-fused acceptor moieties that may assist the development of high performance organic electronic devices.
