摘要
Various hydrophilic gamma-cyclodextrin (CD) thioethers, containing neutral or ionic side arms were found to form molecular disperse solutions of C-60 in water reaching concentrations of 15 mg/L. Equilibrium state was approached after seven days without the use of organic cosolvents. The 1:2 stoichiometry of the C-60/gamma-CD thioether complexes was demonstrated by a parabolic phase-solubility diagram. In contrast, native gamma-CD forms nanoparticles with C-60. Particle sizes of C-60 were determined by dynamic light scattering.
