Abstract:
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 mgmL, 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.
