The paper presents the results of a study of the stability of aqueous solutions of inclusion complexes of hydroxypropyl-β-cyclodextrin with diisopropylphenol in various systems by the Higuchi-Connors phase solubility method. The phase solubility profiles for each system corresponding to the AN type are determined graphically, and the stability constants of the resulting inclusion complexes are calculated. An aqueous solution containing 0.2 % Tween 80 and 0.2 % mannitol was selected as the optimal condition for obtaining the hydroxypropyl-β-cyclodextrin inclusion complex with diisopropylphenol.

Cyclodextrin Inclusion Complex

The inclusion complex of benzo[ a]-12H-phenothiazine (BPHT) and 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) was investigated in an aqueous solution containing 1% ethanol. It was found that the fluorescence emission intensity of the complexed fluorophore is six times larger than that of un complexed species and 1.5 times higher than that in pure ethanol. BPHT forms a 1:1 complex when included in the HP-β-CD. An association constant of the complex of 100±20 M−1 was calculated by using the Benesi–Hildebrand treatment of fluorescence emission data. A discussion based on AM1 semiempirical calculation of BPHT geometry indicates that the inclusion of BPHT in HP-β-CD is partially achieved, probably by the hydrophobic aromatic moiety of the molecule.
