 A similar exercise aimed at construction of a C78 cage in 2008 (but leaving out the precursor's halogens) did not result in a sufficient yield but at least the introduction of Stone Wales defects could be ruled out.C60 synthesis through a fluorinated fullerene precursor was reported in 2013 

Fullerene purification is the process of obtaining a fullerene compound free of contamination.In fullerene production mixtures of C60, C70 and higher homologues are always formed.
