开发了一种由带有金刚烷基基团的环蕃与环糊精组成的超分子体系。在中性水溶液中，当主体与α-环糊精组装时，环蕃与TNS等荧光客体的结合亲和力仍保持不变。它的结合位点是显着非极性和良好的屏蔽从散装水相。对于包埋的客体分子，也观察到明显的运动抑制。
A supramolecular system composed of a cyclophane bearing adamantyl moieties with cyclodextrins was developed. The binding affinities of cyclophane toward fluorescent guests such as TNS were effectively retained even when the host was assembled with α-cyclodextrin in neutral aqueous media. Its binding site was significantly apolar and well shielded from the bulk aqueous phase. The marked motional repression was also observed for the entrapped guest molecules.
