Abstract
1, 8-Anilinonaphthalenesulfonic acid (ANS) was included in various cyclodextrin (CyD) cavities forming 1: 1 complexes in neutral aqueous solution. Addition of excess sucrose or arabinose to the solutions of ANS-CyD complexes changed the fluorescence intensity of ANS. The fluorescence intensity depended on the kind of CyD and saccharide. Decrease in the fluorescence intensity was observed only in the β-CyD-ANS-arabinose system. Remarkable increases were observed in the cases of γ-CyD-ANS-sucrose, β-CyD-ANS-sucrose, and the heptakis- (2, 6-di-O-methyl) -β-CyD-ANS-sucrose system, and slight increase in the γ-CyD-ANS-arabinose system. From the circular dichroism spectra and dependence of fluorescence intensity on saccharide concentration, saccharides seem to stay nearby the rim of the CyD cavity owing to hydrogen bonding between the hydroxyl groups of saccharides and those on the CyD rim, which makes the environment of the ANS molecule more hydrophobic and fluorescence intensity strong.
