Abstract
Ethyl benzoate was found to complex with cyclodextrins in formation of vesicles for the first time. These vesicles were characterized by transmission electron microscopy and dynamic light scattering. The complex stoichiometry, the stability constant and conformations of ethyl benzoate · cyclodextrins in aqueous solution were investigated by ultraviolet and nuclear magnetic resonance analyses. The vesicle system was prepared without complicated synthesis. This kind of vesicles prepared by cyclodextrin inclusion complexes could be applied in many fields.
