Cryptands, carcerands, polyoxometalates, and molecular capsules are cagelike hosts that complex guests through encapsulation. Following the discovery of a nanometer scale supramolecular shell-like spheroid, these and other shell-like hosts were structurally classified. Their frameworks may be catalogued according to principles of solid geometry. This has led to the identification of hosts that have not yet been synthesized or discovered (such as the cuboctahedron shown; X=O, S) and should lead to the design of additional container assemblies.
笼状化合物、笼状分子、多金属氧酸盐和分子胶囊是通过包合作用来络合客体的主体。在发现纳米级超分子壳状类球体之后，这些和其他壳状主体被进行了结构分类。根据立体几何的原理，它们的骨架可以被分类。这就导致了一些尚未被合成或发现的主体的出现（如图中所示的立方体八面体；X=O，S），并应该导致更多的容器组装的设计。
