基于碗烯的多环芳烃及自组装研究进展

Recent advances in polycyclic aromatic hydrocarbons and self-assembly based on corannulene

碗烯(corannulene,C_(20)H_(10))是一种由5个六元环围绕着一个中心五元环构成的呈碗状芳香结构的多环芳烃分子.碗烯可以翻转、接受电子以及形成主-客体络合物.由于这些独特性质,碗烯成为构筑有机功能材料的一种十分特殊的原料,并且基于碗烯的有机功能材料已经展现出了独特的性质和广阔的应用前景.本文概述了过去20年来,碗烯在多环芳烃和自组装等领域的研究进展,重点介绍了融合的平面和螺旋分子片段及空间几何结构等因素对这类非平面共轭多环芳烃分子的性质产生的影响.

Corannulene(C_(20)H_(10)) is a polycyclic aromatic hydrocarbon in which five six-membered rings surround a central five-membered ring to construct a bowl-shaped aromatic structure. Corannulene can invert, accept electrons and form host-guest complexes. Due to these unique features, corannulene presents an interesting building block in the construction of organic functional materials. More importantly, these materials usually have excellent properties and broad application prospects. This review summarizes the literature of the past two decades and covers new progress in polycyclic aromatic hydrocarbons(PAHs) and self-assembly based on corannulene. The different fusions of planar and helical subunits and geometric structures that have an influence on the properties of PAHs are also highlighted.
