A pseudorotaxane, a rotaxane and a catenane are provided. The pseudorotaxane includes at least a macrocyclic host molecule, a guest molecule, and a metal ion. The host molecule contains at least a binding unit and an aromatic linking spacer. The guest molecule has at least a recognition unit. The metal ion is used to template the threading of the guest molecule through the macrocycle host molecule by coordinating to a binding pocket formed from the binding unit of the macrocycle and the recognition moiety of the guest molecule. Rotaxanes or catenanes can be synthesized from the pseudorotaxane complexes, with or without the metal template ion in their molecular structures.
提供了伪轮烷、轮烷和猫烷。伪轮烷包括至少一个大环主分子、一个客体分子和一个金属离子。主分子至少含有一个结合单元和一个芳香连接间隔。客体分子具有至少一个识别单元。金属离子通过协同作用于大环的结合单元和客体分子的识别基团形成的结合口袋,用于模板化客体分子通过大环主分子的穿线。轮烷或猫烷可以从伪轮烷复合物中合成,其分子结构中可以有或没有金属模板离子。
