The association constants (K_a),free energy (△G⁰),enthalpy (△H⁰)and entropy (△S⁰)changes were determined for the inclusion complexation of β-cyclodextrin with a series of 1-substituted naphthalenes in aqueous solution.The △H⁰-T△S⁰ plot for the β-cyclodextrin complexes with naphthalene derivatives show a linear relationship with slope of 0.98 and intercept of 14.67.The results were discussed in terms of enthalpy-entropy compensation.
