A quinoidal small-molecule semiconductor QDPPBTT was synthesized. Organic thin-film transistor (OTFT) devices based on QDPPBTT showed an electron mobility as high as 0.13 cm V s and I /I ratio of 10 under ambient conditions. We suggested that 2D extended π-conjugation and quinoid-enhancing effect had an important role in electron mobility and stability of n-type FET devices, which might be a good strategy in designing new material systems.
合成了一种醌型小分子半导体QDPPBTT。基于QDPPBTT的有机薄膜晶体管（OTFT）器件在环境条件下显示出高达0.13 cm² V⁻¹ s⁻¹的电子迁移率和10的Ion/Ioff比。我们认为二维扩展π共轭和醌增强效应在n型场效应晶体管器件的电子迁移率和稳定性方面具有重要作用，这可能是设计新材料系统的一个良好策略。
