CaX2(X=BR−，I−)的选择性离子对结合是通过含有同位阴离子-π结合位点和五甘醇结合位点的三位受体实现的。该受体与CaI2形成独特的溶剂分离离子对络合物，与CaBr2形成接触离子对络合物，可用于选择性地溶解有机溶剂中的卤化钙。
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.
