摘要
有机场效应晶体管具有质量轻、价格低廉、可大面积制备和可应用于柔性基底的特点,其在柔性显示,智能卡,传感器,射频商标等领域具有潜在的应用~([1])。有机半导体材料作为有机场效应晶体管的基本结构单元决定着器件的性能。近年来,尽管有机半导体的研究取得了飞速的发展~([2-3]),但综合性能优异的有机半导体,特别是n-型有机半导体的缺乏仍然是制约有机晶体管应用的瓶颈。基于有机晶体管的研究现状和面临的困难,我们设计合成了系列并噻吩n-型有机半导体材料,这些材料可以方便的通过溶液方法构筑薄膜晶体管,而且所构筑的器件显示了高的电子迁移率(最高迁移率达7.7 cm~2/Vs)和稳定性~([4-10])。此外我们还对烷基链结构对噻吩醌式有机半导体的分子堆积和器件性能的关系进行了研究。
Solution-processable organic semiconductors(OSCs) have attracted great interests due to their potential applications in large-area,flexible and low-cost thin film transistors.Though great progress has been made on n-channel organic transistors recently,and some of the solution processable n-channel OSCs exhibited mobility higher than 1.0 cm~2/Vs,most of them required high temperature thermal annealing(>150 ℃) and/or special device configuration which hindered the fabrication of devices on flexible substrates at low cost.Considering the important roles of n-channel OSCs in complementary metal-oxide-semiconductor(CMOS)-like digital integrated circuits,it is vital to develop solution-processable n-channel OSCs that can achieve high performance at low thermal annealing temperature or even without thermal annealing.Recently,we have developed series of tetracyanothienoqumoidal type organic semiconductors.The solution processed transistors of tetracyanothienoquinones displayed high electron mobility up to 7.7 cm~2/Vs.In the presentation,the syntheses,aggregation behaviors and transistor performances of tetracyanothienoquinones will be reported.
