研究了葫芦[5]脲及其镧系元素封端分子胶囊对硝酸根和氯离子的选择性包封行为。使用荧光光谱法，无金属主体已被证明选择性地包含硝酸根离子。相反，镧系元素封端的分子胶囊显示出优先包含氯离子。具有 La(III) 封端分子胶囊的硝酸盐和氯化物包合物的固态结构已通过晶体学测定。
The selective encapsulation behavior of cucurbit [5]uril and its lanthanide-capped molecular capsule toward nitrate and chloride ions has been investigated. Using fluorescence spectroscopy, the metal-free host has been demonstrated to selectively include nitrate ion. In contrast, the lanthanide-capped molecular capsule showed preference toward the inclusion of chloride ion. Solid-state structures of the nitrate and chloride inclusion complexes with the La(III)-capped molecular capsule have been crystallographically determined.
