Abstract
[GRAPHICS] Anion binding by neutral hosts in organic solvents can be inhibited by the presence of alkali metal cations. The binding inhibition is due to salt ion -pairing which increases in the order Cs+ < K+ < Na+. The binding inhibitio n can be reversed by using heteroditopic hosts that simultaneously bind bot h the metal cation and the anion. The largest cation-induced enhancements a re observed with the less basic anions.
