Abstract
beta-Cyclodextrin (beta-CD) functionalized with diaza-18-crown-6 at primary face shows 7-10 fold greater binding constants for aromatic ammonium ions in aqueous media than the unmodified beta-CD by the cooperative binding of the aromatic group to beta-CD and ammonium group to crown ether moiety.
