Abstract

A survey of solvents with a wide variation of solubility for C60 and a broad variation in dielectric constant was investigated for possible red shifting of the linear absorbance spectra. Initial analysis shows that very small shifts are achieved. Molar extinction spectra were measured for C60 in each solvent in both the standard mode and with an integrating sphere. Comparison of the two methods has shown strong scattering effects. The UV-vis spectra revealed some broadening in the bands and in some cases supression of strong C60 bands. Fluorescence spectra also show broadening of bands and new fluorescence minima in some solvents indicating formation of complexes between the C60 and those solvents that contain nitrogen.
