Like typical alkenes, fullerenes can be oxidized by ozone. Epoxidation
reaction takes place on C60, and C60On (n=1-5) are formed. Mass spect
rometry and chromatography identified the stable existence of two isom
ers for the dioxides and three for the trioxides in the product mixtur
es. At lower temperatures, fragmentation occurs and results in the for
mation of the polar products. C70 and carbon nanotubes also react with
ozone but at a much slower rate.
