A process for purification of the previously insoluble empty fullerenes and endohedral metallofullerenes was developed, based on sublimation from the soot and subsequent solubilization by electrochemical reduction. The ...

While fullerenes form in yields exceeding 30% by mass when a laser generated pure carbon vapor is allowed to condense under annealing conditions, more than 70% of all vaporized carbon assembles in the form of single-wall ...
