Abstract
The equilibrium constants (K) for the inclusion complex formation of β-cyclodextrin (β-CD) with Methyl Orange (MO) and substituted azoanilinium chlorides were determined spectrophotometrically. Based on the results, the substituent effect on the inclusion complexation of β-CD with azoanilinium chlorides was discussed in detail. Further, the solvent effects on the inclusion complexation of MO with β-CD and heptakis(2,6-di-O-methyl)- β-cyclodextrin(DM-β-CD) were examined in aqueous organic mixtures with water-miscible organic compounds (dimethylsulfoxide, acetonitrile, N, N-dimethylformamide, and acetone). It was found that the K value for the inclusion complex formation with β-CD and DM-β-CD decreases remarkably with increasing ratio of organic solvents, dependent of the surface tension of solvent mixtures.
