摘要：

从物质结构的角度来看, 有机/聚合物半导体是以组合仔-轨道为主要电荷载流子输运通道的分子凝聚态固体. 其化学本质是仔系统, 可以通过仔-轨道的分子工程技术来巧妙地合成. 本文以自己课题组的工作为主线, 从物理有机化学的角度, 阐述了有机/聚合物半导体设计的基本四要素, 即电子结构、空间位阻、构象与拓扑以及超分子弱作用. 同时, 总结了四个单元要素在有机/聚合物半导体设计方面的研究进展, 并展望了四元设计正成为科学家的一种重要思维模式.

Abstract:

Organic semiconductors are charge carrier-transporting molecular solids with π-orbital channels. Organic semiconductors are π-systems that can be created via the molecular engineering of π-orbitals. In this review, we present a pattern in physical organic chemistry by summarizing four fundamental elements of organic/polymeric π-semiconductors according to our previous work. These include electronic structure, steric hindrance, conformation and topology, and supramolecular interactions. Advances in the field of organic/polymeric π-semiconductors with respect to these four elements are highlighted to demonstrate the impact on device functionality and performance. We also provide an outlook of the four-element principle as a basic thinking pattern in scientific research.

Key words: Organic semiconductor, Conjugated polymer, π-System, Electronic structure, Steric hindrance, Conformation and topology, Supramolecular interaction, Four-element design
