摘要
The composition and stability constants of 2:1 inclusion compounds of β-Cyclodextrin (β-CD ) with guest molecules were obtained approximately by NMR method,for the first time, through changes of chemical shifts for H-3 of β-CD cavity. The guest molecules in the present work are diphenyl and its derivatives (p-hydroxydiphenyl; 2,2'-dihydroxydiphenyl;4,4'-dihydroxydiphenyl ).
