中文摘要： n-型有机半导体材料是有机逻辑互补电路应用的基础。目前n-型有机半导体材料的发展远远滞后于p-型有机半导体材料，高性能的n-型有机半导体材料数目还很少。n-型有机半导体材料的缺乏已经成为有机晶体管发展和应用的瓶颈。发展具有高迁移率，可溶液加工，并且器件性能稳定的新型n-型有机半导体材料不仅会极大推进有机晶体管的发展，还会加深我们对n-型有机半导体材料中所存在的如材料分子结构与器件空气稳定性的关系等基本科学问题的理解。本申请在综合文献和申请人以往工作的基础上，从降低材料的LUMO能级，增加分子间相互作用力和电子偶合度等方面入手，借助醌式结构具有低的LUMO能级和噻吩结构单元具有强的分子间相互作用力的特点，采用发展新结构单元，新构型等方法，设计、合成系列新型噻吩类醌式n-型有机半导体材料，构筑其薄膜、微纳单晶器件，测试器件性能，并对n-型有机半导体材料领域的基本科学问题开展研究。

英文摘要： N-channel organic semiconductors are the base of organic logic circuits. Currently, the development of n-channel organic semiconductors are largely lagged behind that of p-channel ones, and high performance n-channel organic semiconductors are rare. The absence of high performance n-channel organic semiconductors has become the bottleneck of organic transistors. The discovery of high-performance, solution-processable and ambient-stable n-channel organic semiconductors is not only crucial for the development of organic transistors, but also helpful to understand the basic scientific questions (such as the relationship between molecular structure and the air stability of transistors) of organic electronics. Based on the literatures and our previous works, we will start our project from design and syntheses new type of n-channel organic semiconductors with lower LUMO energy level and stronger intermolecular interactions and electronic coupling. Considering that quinoidal type compounds exhibit low LUMO energy and thiophene displays strong intermolecular interactions and electronic coupling, we will design and synthesize series of thiophene-based quinoidal compounds in which new conjugated units and new configurations will be adopted. After that thin film and micro/nano-sized single crystal transistors will be fabri
