英文摘要: Balanced carrier transport is observed in acceptor-acceptor (A-A') type polymer for ambipolar organic thin-film transistors (OTFTs). It is found that the incorporation of two electron-accepting moieties (BTz and IIG) into a polymer main chain to form A-A' polymer PIIG-BTz could lower highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) levels and facilitate good molecular stacking of the polymer. Ambipolar transistor behaviour for PIIG-BTz, with the balanced hole and electron mobilities of 0.030 and 0.022 cm(2) V-1 s(-1) was observed in OTFT devices, respectively. The study in this work reveals that the utilization of acceptor-acceptor (A-A') structure in polymer main chain can be a feasible strategy to develop ambipolar polymer semiconductors.
