Supramolecular self-assembly by hybrid macrocycles containing both cucurbit[m]uril (CB[m]) and pillar[n]arene was discussed and summarized in this review. Due to different solubility, diverse-sized cavities, and various driving forces in recognizing guests, the role of CB[m] and pillar[n]arene in such hybrid macrocyclic systems could switch between competitor in capturing specialized guests, and cooperator for building advanced hybridized macrocycles, by controlling their characteristics in host-guest inclusions. Furthermore, both CB[m] and pillar[n]arene were employed for fabricating advanced supramolecular self-assemblies such as mechanically interlocked molecules and supramolecular polymers. In those self-assemblies, CB[m] and pillar[n]arene played significant roles in, e.g., microreactor for catalyzing particular reactions to bridge different small pieces together, molecular "joint" to connect different monomers into larger assemblies, and "stabilizer" in accommodating the guest molecules to adopt a favorite structure geometry ready for assembling.
本综述讨论并总结了由同时包含葫芦脲[m]（CB[m]）和柱[n]芳烃的混合大环化合物形成的超分子自组装。由于溶解性不同、空腔尺寸多样以及识别客体时的各种驱动力，通过控制它们在主客体包合中的特性，CB[m]和柱[n]芳烃在这种混合大环体系中的作用可以在捕获特定客体时的竞争者与构建高级杂化大环时的合作者之间切换。此外，CB[m]和柱[n]芳烃都被用于制造先进的超分子自组装体，如机械互锁分子和超分子聚合物。在这些自组装体中，CB[m]和柱[n]芳烃发挥了重要作用，例如，作为催化特定反应的微反应器，将不同的小片段连接在一起；作为分子“接头”，将不同的单体连接成更大的组装体；以及作为“稳定剂”，容纳客体分子以采用有利于组装的结构几何形状。
