A simple method of preparing water-soluble C[sub 60] at room temperature has been developed by complexing it with [gamma]-cyclodextrin. By this method concentrations as high as 1.0 x 10[sup [minus]4] mol dm[sup [minus]3] of C[sub 60] can be solubilized in water. The complex is characterized by thermogravimetric, optical absorption, and powder X-ray diffraction analysis. The optical absorption spectrum, extinction coefficient, and equilibrium constant for a 2:1 (CD:C[sub 60]) complex of C[sub 60] with [gamma]-cyclodextrin are reported. With the help of picosecond and nanosecond laser photolysis techniques, the triplet characteristics of the CD-C[sub 60] complex are determined. 21 refs., 5 figs., 1 tab.
