Differences in the affinity of anion guests for the crown of ammonium groups and nonpolar cavity of host 2. Anions are shown in the order of decreasing affinity for the crown. The black arrows for the PF6− and CF3SO3− data indicate that binding to the crown is stronger than the shown value (5000 M−1).
