Prepared in only three synthetic steps, a non-multimacrocyclic heteroditopic receptor binds potassium salts of halides and carboxylates with unusually high cooperativity, suggesting salt binding as associated ion-pairs. Unprecedented extraction of highly hydrophilic KAcO salt from water to organic solution is also demonstrated.

一种非多环大环异位受体，可协同结合并有效提取KAcO盐†

仅需三个合成步骤即可制备，一个非多环大环异位受体以异常高的结合力结合卤化物和羧酸盐的钾盐，表明盐结合为相关的离子对。还展示了前所未有的高亲水性KAcO盐从水到有机溶液的萃取。
