The carbon atoms within a Fullerene molecule are sp2 and
sp3 hybridized, of which the sp2 carbon are responsible for the
considerably angle strain presented within the molecule. C60
and C70 exhibit the capacity to be reversibly reduced with up
to six electrons. This high electron affinity results from the
presence of triply-degenerate low-lying LUMOs (lowest
unoccupied molecular orbital). Oxidation of the molecule has
also been observed; nevertheless, oxidation is irreversible. C60
has a localized pi-electron system, which prevents the
molecule from displaying superaromaticity properties
