为了保留平面手性、增强分子识别和构建先进的自组装，设计、制备和研究了包含刚性柱[ n ]芳烃和柔性杯[ m ]芳烃的杂化大环主体，以用于有趣的应用。本综述总结并讨论了构建混合大环结构的不同合成策略。具有刚性芳族双桥的柱[ n ]芳烃二聚体提供了引入杯[ m ]芳烃空腔的可能性，其中平面手性保留在柱芳烃的结构中。混合大环腔增强了分子识别的能力。有趣的是，得到的柱[ n ]芳烃-杯[ m]芳烃可以在固态和溶液相中自组装成“通道”和“蜂窝”，并提供分子结构作为形成机械互锁分子（如轮烷）的轮子。此外，柱[ n ]芳烃和杯[ m ]芳烃也可以偶联在一起，生成嵌入1,3-交替构象和锥形构象杯[ m ]芳烃的柱[ n ]芳烃衍生物，可催化氧化聚合苯胺水溶液。除了通过共价键构建杂环芳烃外，还利用弱超分子相互作用制备了柱状[ n ]芳烃-杯[ m ]芳烃与其他柱状柱类似的复合材料[n ]吡啶鎓和杯状杯[ m ]吡咯，在增强分子识别和捕获溶剂分子方面表现出合理的性能。

Pillar[n]arene–calix[m]arene hybrid macrocyclic structures

To reserve planar chirality, enhance molecular recognition, and build advanced self-assemblies, hybrid macrocyclic hosts containing rigid pillar[n]arene and flexible calix[m]arene were designed, prepared and investigated for interesting applications. This review summarizes and discusses different synthetic strategies for constructing hybrid macrocyclic structures. Pillar[n]arene dimer with rigid aromatic double bridges provided the possibility of introducing calix[m]arene cavities, where the planar chirality was reserved in the structure of pillararene. The capacity for molecular recognition was enhanced by hybrid macrocyclic cavities. Interestingly, the obtained pillar[n]arene–calix[m]arene could self-assemble into “channels” and “honeycomb” in both the solid state and solution phase as well as donate the molecular architecture as the wheel for the formation of mechanically interlocked molecules, such as rotaxane. In addition, the pillar[n]arene and calix[m]arene could also be coupled together to produce pillar[n]arene embeded 1,3-alternate and cone conformational calix[m]arene derivatives, which could catalyze the oxidative polymerization of aniline in aqueous solutions. Except for building hybrid cyclophanes by covalent bonds, weak supramolecular interactions were used to prepare pillar[n]arene–calix[m]arene analogous composites with other pillar-like pillar[n]pyridiniums and calix-like calix[m]pyrroles, exhibiting reasonable performances in enhancing molecular recognition and trapping solvent molecules.
