Calix[4]resorcinarene-based cavitands with a bowl-shaped aromatic cavity are widely used as scaffolds for covalently bound and self-assembled capsules. There are two main categories of calix[4]resorcinarene-based cavitands that are tetrafunctionalized at the upper (wider) rim: one category includes derivatives that have functionalized bridges between pairs of hydroxy groups of the calix[4]resorcinarene, and the second category includes derivatives with functional groups at the 2-position on the resorcinol ring and the methylene bridge between pairs of hydroxy groups. This review describes capsular self-assemblies of the latter type of methylene-bridge cavitands, which are formed through hydrogen bonds, metal-coordination bonds, and dynamic covalent bonds.
基于杯[4]芳烃的空腔具有碗状芳香空腔的空腔分子广泛用作共价键合和自组装胶囊的支架。基于杯[4]芳烃的空腔分子有两种主要类型，它们在上（宽）边缘处四官能化：一类包括在杯[4]芳烃的两个羟基之间具有官能化桥的衍生物，另一类包括在间苯二酚环的 2 位和两个羟基之间的亚甲基桥上具有官能团的衍生物。本文综述了后一种类型的亚甲基桥空腔分子的胶囊自组装，这些自组装是通过氢键、金属配位键和动态共价键形成的。
