Efficient uptake of small to large guests, with a large difference in relative size, is quite rare for synthetic host compounds. Herein we designed and prepared a micellar capsule, composed of bent amphiphiles bearing two adamantyl groups, as a new host with a well-defined nanostructure. Unlike previous covalent, coordination, and hydrogen-bonding hosts, the adamantane-based capsule displays unusual uptake abilities toward spherical molecules with small (∼0.6 nm in diameter; e.g., adamantane) to medium size (∼1 nm; e.g., fullerene) as well as large size (∼3 nm; i.e., metal–organic polyhedra (MOP)), where the size differences are up to 5-fold, in water. Moreover, the resultant MOP-uptaking capsule incorporates medium-sized molecules (e.g., perylene and eosin Y) into the polyhedral cavity to generate ternary core–shell structures.

金刚烷胶囊及其在水中有效吸收高达 3 nm 的球形客体

对于合成的宿主化合物来说，有效吸收小到大的客体，相对大小差异很大，是非常罕见的。在这里，我们设计并制备了一种胶束胶囊，由带有两个金刚烷基的弯曲两亲物组成，作为具有明确纳米结构的新宿主。与以前的共价、配位和氢键主体不同，基于金刚烷的胶囊对具有小（直径约 0.6 nm；例如金刚烷）到中等尺寸（约 1 nm；例如富勒烯）的球形分子表现出不同寻常的吸收能力。以及大尺寸（~3 nm；即金属-有机多面体（MOP）），其中尺寸差异高达 5 倍，在水中。此外，所得的吸尘器胶囊将中等大小的分子（例如，苝和曙红 Y）结合到多面体腔中以产生三元核壳结构。
