Selective ion-pair binding of CaX2 (X = Br-, I-) was realized by a tritopic receptor containing homoditopic anion-π binding sites and a pentaethylene glycol site. The receptor formed an unusual solvent-separated ion-pair complex with CaI2 and a contact one with CaBr2, and can be applied to selectively dissolve calcium halides in organic solvents.
通过包含同二价阴离子-π 结合位点和五乙二醇位点的三聚受体实现了 CaX2（X = Br-，I-）的选择性离子对结合。该受体与 CaI2 形成了一种不寻常的溶剂分离的离子对配合物，与 CaBr2 形成了一种接触配合物，可用于在有机溶剂中选择性溶解卤化钙。
