客人涵盖了一系列的极性进行了检查,他们的能力,结合到一个水溶性的空穴,并触发其组装成一个超分子胶囊。具体地,所检测的客体是:十三烷2,1-十二烷醇3,2-壬氧基乙醇(乙二醇单壬基醚)4,2-(2-己氧基乙氧基)乙醇(二(乙二醇)己基醚)5,2-[2-(2-丙氧基乙氧基)乙氧基]乙醇(三(乙二醇)丙基醚6和双[2-(2-羟基乙氧基)乙基]醚(四(乙二醇))7.在这个系列中,客体6被证明是组装和形成2:1络合物与简单的1:1络合物之间的界限。因此,客体2-5形成相对动力学稳定的胶囊,客体6形成相对于NMR时间尺度不稳定的胶囊,客体7形成简单的1:1络合物。
Guests covering a range of polarities were examined for their ability to bind to a water-soluble cavitand and trigger its assembly into a supramolecular capsule. Specifically the guests examined were: tridecane 2, 1-dodecanol 3, 2-nonyloxy ethanol (ethylene glycol monononyl ether) 4, 2-(2-hexyloxyethoxy) ethanol (Di(ethylene glycol) hexyl ether) 5, 2-[2-(2 propoxyethoxy)ethoxy] ethanol (Tri(ethylene glycol) propyl ether 6, and bis [2-(2-hydroxyethoxy)ethyl] ether (tetra(ethylene glycol)) 7. In this series, guest 6 proved to signify the boundary between assembly and the formation of 2:1 complexes, and simple 1:1 complexation. Thus, guests 2–5 formed relatively kinetically stable capsules, guest 6 formed a capsule that was unstable relative to the NMR timescale, and guest 7 formed a simple 1:1 complex.
