20世纪80年代以来,有机电子学领域的研究取得了很大进展.有机半导体材料凭借其成本低、质量轻、柔性好、易修饰、可大面积溶液加工等特点吸引了学术界以及工业界的极大关注.其中,第三代有机共轭聚合物,给-受体(Donor-Acceptor,简称D-A)共轭聚合物材料的发展尤为迅速.最近,以异靛青(Isoindigo,IID)类结构作为受体片段的D-A共轭聚合物被发现具有优异的性能,特别是在聚合物场效应晶体管器件中获得了最高3.62 cm~2·V~(-1)·s~(-1)的空穴迁移率,其衍生物获得14.4 cm~2·V~(-1)·s~(-1)的空穴迁移率,具有良好的应用前景.综述了近年来国内外关于异靛青结构在聚合物场效应晶体管材料中的应用,对其分子结构设计、器件制备以及构效关系做了详细介绍,希望为今后异靛青类化合物的应用拓展提供指导思路.
Since the 1980s, great progress has been made in the field of organic electronics. Organic semiconductors have attracted the attention of academia and industry due to their low cost, light weight, good flexibility, easy modification, and large-area solution processing The third generation of organic conjugated polymers and donor-acceptor (DA) conjugated polymers have been developed rapidly.Recently, the Isoindigo (IID) The DA conjugate polymer of the acceptor fragment was found to have excellent properties, especially in the field effect transistor device obtained a maximum of 3.62 cm 2 · V -1 · s -1 And its derivatives have a hole mobility of 14.4 cm 2 · V -1 · s -1, which has a good prospect of application. In this paper, the recent progress in the field of isocyanides, Field-effect transistor materials, its molecular structure design, device preparation and structure-activity relationship are described in detail, hoping for the future application of isoindigo compounds to provide guidance.
