Potent solvents for C60 and their utility for the rapid acquisition of 13C NMR data for fullerenes

Described are several solvents for the dissolution of fullerenes. The two best solvents found were 1,2-dichlorobenzene and 1-methylnaphthalene which dissolve C60 up to 24.6 and 33.2 mg/mL, respectively. The solubility data was obtained gravimetrically. Precipitates were obtained when C60 was treated with 1,3,5-trimethylbenzene or 1,2,4-trichlorobenzene. Scanning electron micrographs and thermogravimetric analysis data were obtained on the precipitates and compared to the data obtained for pure C60. The efficacy of 1,2-dichlorobenzene and 1-methylnaphthalene as 13C NMR solvents for fullerene analysis was demonstrated as well as the utility of 1,2-dichlorobenzene for the extraction of higher fullerenes from soot.
