Abstract
A method of extracting fullerenes from a carbon matrix in which they are produced. The method is applicable to both fullerenes that exhibit greater than 0.1 mg/ml solubility in toluene and to fullerenes that are essentially insoluble in toluene, i.e., those exhibiting less than or equal to 0.1 mg/ml solubility. The method disclosed herein extracts more of the soluble fullerenes from the carbon matrix than extraction conducted by solely contacting with solvent. A method is also provided for creating salts of the extracted fullerenes.
