Molecular solubilization of fullerene C(60) in water by γ-cyclodextrin thioethers.

ABSTRACT: Various hydrophilic γ-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)/γ-CD thioether complexes was demonstrated by a parabolic phase-solubility diagram. In contrast, native γ-CD forms nanoparticles with C(60). Particle sizes of C(60) were determined by dynamic light scattering.
