摘　　要：分子张力作为空间设计的重要组成部分正成为调控有机半导体的重要手段。由于分子内产生的拉伸张力、扭曲/弯曲张力以及空间张力而导致p轨道排布重组和构型构象结构发生变化,最近各种几何与拓扑结构的高张力有机半导体材料相继被报道,这使得高张力有机半导体材料成为有机电子领域研究的焦点。为了进一步梳理分子张力在有机半导体材料中扮演的角色与价值,该综述从分子张力的类型、实验与理论量化以及可视化出发,总结了高张力共轭芳烃的分子设计策略、与其光电性能分子张力之间的关系,以及这类新兴材料在光电领域的应用。最后,对高张力共轭芳烃的研究前景进行了展望,阐述了该类材料所面临的机遇与挑战。Molecular strain plays a key role in steric design of organic semiconductors.Molecular strain includes the stretch strain,torsion/bend stain,and steric strain that make special p-orbital arrangements and conformation/configuration change.Recently,diverse highly strained molecules have been reported with various topological and geometric structures,in which organic semiconductors with high strain energy become more and more important in the field of organic optoelectronic materials and their flexible electronics.In order to further get insight into the role of molecular strain in the organic semiconductor materials,the types of molecular strain,theoretical/experimental quantification and visualization are introduced firstly in the review.Then,the strategies of molecular design are summarized for the highly strainedπ-conjugated arenes.Next,the effect of molecular strain on optoelectronic properties of semiconductor materials and their application are highlighted in the field of organic electronics.Finally,the problems faced by highly strained organic semiconductors are discussed and addressed to shed light on the research prospects of these materials.
