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.

Methods for fullerene recovery

A method for recovering small bandgap fullerenes, including metallofullerenes, from soot by passivating individual fullerenes and/or metallofullerenes to an anionic configuration. The addition of extra electrons to a metallofullerene or small bandgap fullerene breaks the interfullerene bonding in the solid material, and the resulting anions are soluble in organic electrochemical solvents. Once dissolved, the small bandgap fullerenes can be plated out or precipitated by returning them to a neutral state.

Isolation of small-bandgap fullerenes and endohedral metallofullerenes

A non-toxic contrast agent for enhancing contrast in in vivo magnetic resonance measurements, comprised of a water-soluble, stable paramagnetic fullerene that is free of paramagnetic metal species. A preferred contrast agent is a fullerol having at least one unpaired electron.

Fullerene contrast agent for magnetic resonance imaging and spectroscopy

A method for recovering small bandgap fullerenes, including metallofullerenes, from soot by passivating individual fullerenes and/or metallofullerenes to an anionic configuration. Thc addition of extra electrons to a metallofullerene or small bandgap fullerene breaks the interfullerene bonding in the solid material, and the resulting anions are soluble in organic electrochemical solvents. Once dissolved, the small bandgap fullerenes can be plated out or precipitated by returning them to a neutral state.
