The versatile synthetic side chain toolbox assists in tuning the OECT parameters by controlling material properties of organic mixed conductors. In this review we critically summarise and evaluate various side chains used throughout OECT materials.
Two D–A type polymers based on the gTDPP as the acceptor and gTVT and gTBTT as the donor have been developed. The donor unit affects the backbone curvature and the aggregation properties of the mixed conductors, regulating their performance in OECTs.
