摘　　要：硅杂环戊二烯并苯有机小分子结构的特殊性,赋予其独特的光电特性,在有机光电功能材料等领域具有广阔的应用前景.其中,并苯的刚性共平面结构可避免构象无序性、扩大π-共轭;硅杂环戊二烯能够形成σ*-π*共轭,可有效降低体系LUMO能级、提高电子亲合势.硅杂环戊二烯并苯有机小分子主要包括苯并噻咯、硅桥联对二苯乙烯衍生物、二苯并噻咯和双硅桥联对-三联苯等.综述了硅杂环戊二烯并苯小分子的合成方法、结构修饰、性能及应用的研究进展,并对今后的研究方向进行了展望.Benzosilole-containing organic molecules have been potentially applied in opto-electronic material fields, due to their unique structural and optical characteristics. The rigid planar structures of acenes prevent conformational disorder, and extend the π-conjugation. Silacyclopentadiene can form σ＊-π＊ conjugation, lowering the LUMO and enhancing the electron affinity efficiently. In this review, benzosiloles, silicon-bridged stilbene derivatives, silafluorenes and bis-silicon-bridged p-terphenyls are focused on. The recent research progress in the synthesis, modification, properties and applications of benzosilole-containing organic compounds is summarized, and the future research of this field is also prospected.
