The development of new types of synthetic macrocyclic hosts is always one of the most important and attractive topics in macrocyclic and supramolecular chemistry. Calixarenes, resorcinarenes, cyclotriveratrylenes, pillararenes, and their analogues are all composed of hydroxy-substituted aromatic rings bridged by methylene or methenyl groups and thus can be considered a type of macrocyclic arenes. Because of their unique structural features, easy functionalization, and wide applications in many research areas, such macrocyclic arenes have become some of the most important and studied synthetic macrocyclic hosts during the last decades.

三萜烯衍生的大环芳烃：从杯芳烃到螺旋芳烃

新型合成大环主体的开发一直是大环和超分子化学中最重要和有吸引力的主题之一。杯芳烃，间苯二烃芳烃，环triveratrylene，柱芳烃及其类似物均由被亚甲基或亚甲基桥接的羟基取代的芳环组成，因此可以认为是大环芳烃的一种。由于其独特的结构特征，易于功能化以及在许多研究领域中的广泛应用，在过去的几十年中，此类大环芳烃已成为一些最重要和研究最多的合成大环宿主。
