An interlocked covalent organic molecular cage with a trigonal-prismatic structure based on anthracene units and imine bonds was synthesized by a template-free and one-pot reaction in a relatively good yield. By comparing the single-crystal structures of the interlocked cage and two additional monomeric cages as reference compounds, a cause of weak supramolecular interaction-induced synthesis was proposed; π···π interactions induce the triphenylbenzene units as the core and anthracenes as side parts close to each other, which provides a possibility of the preorganization for the formation of the interlocked structure.

互锁共价有机分子笼的无模板合成
采用无模板一锅法合成了一种基于蒽单元和亚胺键的三棱柱结构的互锁共价有机分子笼，收率较好。通过比较作为参考化合物的互锁笼和另外两个单体笼的单晶结构，提出了弱超分子相互作用诱导合成的原因；π···π相互作用导致三苯苯单元为核心，蒽为侧部，相互靠近，为形成互锁结构提供了预组织的可能。
