Abstract

A heteroditopic receptor having crown ether and trifluoroacetylcarboxanilide groups selectively recognizes both potassium and cyanide ions in acetonitrile with an association constant of as high as Ka = 1.9 × 107 M−1 through a highly cooperative ion-pair interaction, resulting in two orders of magnitude enhancement in the binding affinity.
