摘要
Spectrofluorometric titration and continuous variation were used to study supramolecular inclusion complexes of β-CD and its derivatives with 2-p-toluidinglnaphthalene-6-sulfonate(TNS).The stoichiometry,stability constants and configuration of supramolecular inclusion complexes were discussed.The results suggest that β-CD and its derivatives form 1∶1 supramolecular inclusion complexes with TNS in aqueous solutions.The hydrophobic interactions and van der Waals forces determine the stability of supramolecular inclusion complexes.The size fit between the hosts and the guest plays important roles in the formation of the supramolecular inclusion complexes.

The results suggest that β-CD and its derivatives form 1 ： 1 supramolecular inclusion complexes with TNS in aqueous solutions. The hydrophobic interactions and van der Waals forces determine the stability of supramolecular inclusion complexes. The size fit between the hosts and the guest plays important roles in the formation of the supramolecular inclusion complexes.
