Abstract
A simple method of preparing water-soluble C-60 at room temperature ha s been developed by complexing it with gamma-cyclodextrin. By this met hod concentrations as high as 1.0 X 10(-4) mol dm(-3) of C-60 can be s olubilized in water. The complex is characterized by thermogravimetric , optical absorption, and powder X-ray diffraction analysis. The optic al absorption spectrum, extinction coefficient, and equilibrium consta nt for a 2:1 (CD:C-60) complex of C-60 With gamma-cyclodextrin are rep orted. With the help of picosecond and nanosecond laser photolysis tec hniques, the triplet characteristics of the CD-C-60 complex are determ ined.
