[reaction: see text] It was found that a cylindrical macrotricyclic host containing two dibenzo[24]crown-8 cavities could self-assemble with two dibenzylammonium salts to form a stable 1:2 complex in solution and in the solid state, in which multiple hydrogen-bonding and pi-pi stacking interactions between the host and the guest played an important role. Furthermore, a series of dendritic pseudorotaxanes were constructed and structurally studied.
[反应：见正文] 发现含有两个二苯并[24]冠-8空腔的圆柱形大环主体能够与两种二苄基铵盐自组装，在溶液和固态中形成稳定的1:2配合物，其中主体与客体之间的多重氢键和π-π堆积相互作用起重要作用。此外，构建了一系列树枝状准轮烷并对其结构进行了研究。
