Anion binding by neutral hosts in organic solvents can be inhibited by the presence of alkalimetalcations. The binding inhibition is due to salt ion-pairing which increases in the order Cs(+) < K(+) < Na(+). The binding inhibition can be reversed by using heteroditopic hosts that simultaneously bind both the metalcation and the anion. The largest cation-induced enhancements are observed with the
