The inclusion compounds of β-cyclodextrin(host) with diphenyl and its derivates (p-hydroxydiphenyl; 2,2'-dihydroxydiphenyl; 4,4'-dihydroxydiphenyl) (guest) were prepared. The properties of these compounds were investigated by using the thermogravimetry-differential thermal analyses, powder X-ray diffractometry, nuclear magnetic resonance and infrared spectroscopy. The experimential results demonstrated that all the inclusion compounds were found to be 2:1 and their inclusion equilibrium contants (K) were obtained approximately by NMR method. The possible structure and the driving force for these compounds were discussed.
