摘要：

The inclusion complexes of styrene and a-methyl-styrene with beta-cyclodextrin (P-CD) were investigated by using [H-1] NMR titration in solution and X-ray diffraction (XRD) analysis, thermo-gravimetric analysis (TGA), elemental analysis (EA) in the solid state. The inclusion process has been studied by using PM3 quantum-mechanical semi-empirical method. The calculated results are in agreed with the experimental data. All results show that alpha-methyl-styrene has stronger interaction with P-cyclodextrin than styrene does, so the complex of beta-CD-alpha-methyl-styrene is more stable. (C) 2003 Elsevier B.V.
