Complex formation between benzene carboxylic acids and β-cyclodextrin in aqueous solutions at 290–300 K was studied using
UV spectroscopy. The formation of 1:1 supramolecular inclusion compounds β-cyclodextrin-benzene and β-cyclodextrin-salicylic
acid was found. Stability constants (K
s) of the complexes and thermodynamic parameters for formation of the inclusion compounds (ΔG, ΔH, and ΔS) were calculated.
Key words supramolecular chemistry - UV spectroscopy - β-cyclodextrin - benzoic acid - salicylic acid - encapsulation - inclusion complexes
