摘　　要：近年来,由于含硅桥联并环π-共轭体系的独特结构特性以及分子的多样性、可设计性,在光电功能材料的研究中得到越来越多的关注。并环结构赋予体系以刚性共平面结构,使其共轭较非并环结构母体进一步增强,而硅桥的引入则可影响分子的电子结构进而影响材料的光电性能。母体结构及硅桥联方式的选择为分子结构设计和光电性能的改进提供了较大的空间。本文根据母体结构的不同,对硅桥联联苯体系、硅桥联噻吩体系以及硅桥联对二苯乙烯齐聚物体系光电功能材料的研究进展进行了综述。Recent years has view increased interesting in silicon-bridge containing fused rings π-conjugated systems for optic and electronics, due to their unique structure properties, as well as diversity of molecules. In these molecules, flatting the π-conjugated framework by fused rings enhances the π-conjugation, and incorporation of silicon-bridge contributes to the electronic structure thus for material properties. By choice of parent framework and style of silicon-bridge, various molecules with different properties can be designed. Research progresses in silicon-bridge containing ring fused π-conjugated systems for opto-electronic materials, in terms of their parent framework, including diphenyl, dithieno, and p-phenylenevinylene systems are reviewed in this paper.
