Abstract : The rapid progress in host-guest chemistry involving macrocycles has been due in no small part to the availability of reliable and extensive thermodynamic data for a large number of host-guest systems. Although valuable information concerning these systems can be derived from delta H and delta S values, few calorimetric data have been reported for host-guest systems. This report summarizes the log K, delta H, delta S, and delta log K values for the interaction of a number of chiral 18-crown-6 host molecules for the enantiomers of alpha-(l-naphthyl)ethylammonium and alpha-(phenyl)ethylammonium perchlorate salts.
