【Abstract】 The Vis research result of binding processes of host β-cyclodextrin and guest di-substituted benzenes in aqueous solution is reported in this article. Equilibrium constants under varied temperature and thermodynamic function variables under 298K of the binding processes were determined by the experiment. It shows that the hydrophobicity of varied aromatic substituted group and the configuration of guest have played an important role in the binding interaction between host and guest.更多还原
