环对苯撑的超分子化学和机械立体化学

Supramolecular chemistry and mechanostereochemistry of cycloparaphenylenes

环对苯撑因其径向共轭的π电子体系、刚性的环状空腔和独特的光电性质而广受关注.本文围绕环对苯撑及其衍生物的主客体化学、自组装以及机械互锁结构三个方面展开,着重介绍了环对苯撑及其衍生物的基于π-π相互作用、CH-π相互作用和金属配位作用的主客体化学,固态中的自组装,以及轮烷、索烃和三叶结等机械互锁分子.最后,对环对苯撑及其衍生物的超分子化学和机械立体化学进行了总结与展望.

Cycloparaphenylenes have attracted considerable attention due to their radially conjugatedπ-electron system,rigid cyclic cavity,and unique optoelectronic properties.This review focuses on three aspects of cycloparaphenylenes and their derivatives:host-guest chemistry,self-assembly,and mechanically interlocked structures.Specifically,we emphasize(1)the host-guest chemistry of cycloparaphenylenes and their derivatives based onπ-πinteractions,CH-πinteractions,and metal coordination,(2)supramolecular self-assembly in solid states,and(3)mechanically interlocked molecules including rotaxanes,catenanes,and trefoil knot.Finally,the challenges and prospects of cycloparaphenylenes and their derivatives in the fields of supramolecular chemistry and mechanostereochemistry are discussed.
