Abstract
A simple method of preparing water-soluble C60 at room temperature has been developed by complexing it with γ-cyclodextrin. By this method concentrations as high as 1.0×10-4 mol dm-3 of C60 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:C60) complex of C60 with γ-cyclodextrin are reported. With the help of picosecond and nanosecond laser photolysis techniques, the triplet characteristics of the CD-C60 complex are determined.
