Abstract
Cyclodextrins (beta- and gamma-CyDs) were precipitated in an aqueous m edium at 25-degrees-C in the presence of a naphthalene (N)-biphenyl (B ) mixed guest. The N/B molar ratio in the precipitates was found to be governed by S(N).K(N) (S(B).K(B))-1, where S refers to the solubility of the guest in water and K to the 1 : 1 association constant of the CyD-guest.
