NMR diffusion measurements provide unequivocal proof that the resorcinarene 1b self-assembles spontaneously into a stable hexamer capsule in chloroform solution by encapsulating several chloroform molecules, which occupy different chemical positions. Although the affinity of tetrahexylammonium bromide (2a) toward the cavity of the hexamer is much higher than that of the chloroform molecules, it was found that the same amount of DMSO is needed to disrupt the two hexamers, thus suggesting similar stabilities for these two supramolecular capsules.
核磁共振扩散测量提供了明确的证据，表明间苯二酚芳烃1b在氯仿溶液中通过包封几个占据不同化学位置的氯仿分子，自发地自组装成一个稳定的六聚体胶囊。尽管四己基溴化铵（2a）对六聚体空腔的亲和力远高于氯仿分子，但发现破坏这两种六聚体需要相同量的二甲基亚砜，因此表明这两种超分子胶囊具有相似的稳定性。
