Organic semiconductors received more and more attention in the past few years. Development some novel chromophore with the strong electron-deficient to construct donor–acceptor polymers plays a crucial role for the development of the organic semiconductors. A new acceptor indaceno[1,2-:5,6-′]dithiophene)-2,7-diylbis(methan-1-yl-1-ylidene))bis(6-bromo-indolin-2-one) (IDTI, M1), as well as a IIDT-based polymer P1 were designed in this work, and for the first time applied in the OFET. The results shows that the P1 present not only a strong aggregation, but also a suitable highest occupied molecular orbital (HOMO) energy level. As a consequent, the P1 exhibited a p-type behavior with the hole mobility up to 0.29 cm V s. This work demonstrated that the IDTI chromophore is a promising electron-deficient block for the constructing donor–acceptor high performance semiconductor polymers.

用于 p 型有机场效应晶体管的 IDTI 共聚物

有机半导体在过去几年受到越来越多的关注。开发一些具有强缺电子性的新型发色团来构建供体-受体聚合物对于有机半导体的发展起着至关重要的作用。新受体茚并并[1,2-:5,6-′]二噻吩)-2,7-二基双(甲烷-1-基-1-亚基))双(6-溴-二氢吲哚-2-酮)(IDTI这项工作设计了基于IIDT的聚合物P1，并首次应用于OFET。结果表明，P1不仅表现出强烈的聚集性，而且具有合适的最高占据分子轨道（HOMO）能级。结果，P1表现出p型行为，空穴迁移率高达0.29 cm V s。这项工作表明，IDTI 发色团是一种有前途的缺电子嵌段，可用于构建供体-受体高性能半导体聚合物。
