[5]Pseudorotaxanes can be obtained by self-sorting using heteroditopic guests and various cucurbituril homologues as hosts. The assembly and chemically induced disassembly of the pseudorotaxanes can be monitored by measuring the fluorescence of the anthracene guest in solution. Mass spectral evidence for the supramolecular assemblies is obtained in the gas phase. The disassembly in the gas phase can be achieved by collision-induced dissociation leading to the corresponding [2]- and [3]pseudorotaxanes.
[5] 伪轮烷可通过使用异双位点客体和各种葫芦脲同系物作为主体进行自分类来获得。伪轮烷的组装和化学诱导拆卸可通过测量溶液中蒽客体的荧光来监测。在气相中获得了超分子组装体的质谱证据。气相中的拆卸可通过碰撞诱导解离实现，从而得到相应的[2]-和[3]伪轮烷。
