Abstrakt: The line-broadening of 81Br NMR signals observed in the presence of CyDs was applied to evaluate their binding abilities toward inorganic anions in aqueous solutions. The apparent association constants of α -CyD with anions have been found to decrease in the order SCN−> ClO4−> I−> NO3−> Br−F−> Cl−.
