The design, synthesis, and characterization of new organic semiconductors (OSCs) are important aspects for the development of next-generation optoelectronic devices. Structurally, organic semiconductors based on π-conjugated molecules can be easily modified via rational synthesis to tune multi-level self-assembled structures and discover novel chemical, optical, and electronic properties. Heteroarenes, which contain chalcogens and nitrogens in fused aromatic rings, are being developed as promising semiconducting materials for applications in a variety of electronic devices due to their outstanding optoelectronic properties. We highlight recent approaches toward realizing high performance p-channel field effect transistors based on linear heteroacenes and heteroatom annulated polycyclic aromatics (PAHs) as key functional components. These comprehensive, but carefully orchestrated approaches simultaneously address (i) practical synthesis, (ii) tunable self-assembled packing arrangement as well as (iii) high electronic performance.
新型有机半导体(OSC)的设计、合成和特性研究是开发下一代光电器件的重要方面。在结构上,基于π共轭分子的有机半导体可以通过合理的合成进行轻松修饰,以调节多层次自组装结构并发现新的化学、光学和电子特性。杂芳族化合物,其在稠合芳环中包含硫属元素和氮,由于其出色的光电性能,正在被开发为各种电子器件中应用的有前途的半导体材料。我们重点介绍了最近在基于线性杂芳族和杂原子稠合多环芳烃(PAH)作为关键功能组件的高性能 p 沟道场效应晶体管方面的实现方法。这些全面的方法,同时精心协调了(i)实际合成、(ii)可调自组装堆积排列以及(iii)高电子性能。
