UV-Vis and continuous variation plot method were used to study the complexation of γ-cyclodextrin with bromocresol green, and the stoichiometric ratio of the complexation was to be 1∶2. Thermodynamic analysis results show an inverse relationship between temperature and complexation constant, and the change of enthalpy, entropy and free energy of the complexation were -39.988 kJ/mol, 86.400 J/ and -14.245 kJ/mol, respectively, which indicating that hydrophobic effect was the main force to form the complexes.γ-Cyclodextrin and bromocresol green complexes were examined by nuclear magnetic resonance, infrared spectrum and molecular modeling analysis, and was may be the group included in γ-cyclodextrin.
