Abstract:

The solvation of the system of C60-toluene is studied by determining UV-Vis absorption spectrum, it is found that the maximum absorption wavelength of C60 exhibits red-shift in toluene medium. Viscosity measurement gives the thickness of the solvation layer as 0.85 nm. At temperature 30℃, the value of the diffusion coefficient is 3.12× 10-10m2•s-1 which is an order of magnitude less than that of small molecules. The results above indicate that C60 is solvated in toluene medium.

Key words: Fullerence, Solvation, Diffusivity, Viscosity
