A new class of ambipolar donor-acceptor π-conjugated polymers based on a dithienocoronenediimide core is presented. Solution-processed top-gate/bottom-contact thin film transistors (TFTs) exhibit electron and hole mobilities of up to 0.30 cm(2)/V·s and 0.04 cm(2)/V·s, respectively, which are the highest reported to date for an ambipolar polymer in ambient conditions. The polymers presented here are the first examples of coronenediimide-based semiconductors showing high organic TFT performances.
本文提出了一类新型的基于二噻吩并[3,2-b:2',3'-d]噻吩并[3,4-b]噻吩并[1,2-a]二咪唑核心的双极给体-受体π共轭聚合物。溶液处理的顶栅/底接触薄膜晶体管（TFT）表现出高达 0.30 cm²/V·s 和 0.04 cm²/V·s 的电子和空穴迁移率，这是迄今为止在环境条件下报道的双极聚合物中最高的。本文所介绍的聚合物是首例基于冠状二酰亚胺的半导体的例子，显示出高的有机薄膜晶体管性能。
