摘　　要：碗状共轭分子是介于平面稠环芳烃和球型富勒烯之间的关键结构,呈现独特的物理和化学性质.本文总结了本课题组在碗状共轭分子"杂化素馨烯"方面的研究进展,包括分子设计的思路、高效合成策略、构效关系分析、化学反应以及基于特征化学反应的可控转化.我们的研究表明,硫族元素杂化素馨烯(TCSs)可作为核心骨架来构筑结构与功能多样化的共轭稠环化合物,包括具有高量子产率的红色荧光分子、具有多重光电功能的勺状分子、新型电子受体、手性共轭分子等.Buckybowls are the key intermediate structures for transforming planar polycyclic aromatic hydrocarbons(PAHs) into fullerenes, and they show unique physical and chemical properties as compared with PAHs and fullerenes.In this review, we summarize our recent progress on the bowl-shaped heterosumanenes, including molecular design rationale, highly efficient synthetic strategies, structure-property relationship, chemical reactions, and controllable transformation. It is proved that trichalcogenasumanenes(TCSs) can serve as a promising scaffold to create unconventional polycylces with structural and property diversity such as red fluorescence hetero-PAHs, molecular spoon with multi-functionality, electron-acceptors, and chiral π-system.
