Fluorescence study of fullerene in organic solvents at room temperature.
At room temperature, fluorescence spectra for C60 in organic solvents of four typical kinds have been reported, which indicate that intensity of fluorescence and fine structure of fluorescence peaks are dependent on the interaction between C60 and solvent. It is shown that the solvents of effective electron donors could make a comparatively strong interaction with fullerenes due to formation of the charge transfer adduct, which could greatly distort the molecular symmetry, leading to the strong and well-resolved fluorescence. The strong fluorescence spectra for C70 in room temperature solutions are also observed.
