The chemical in ambient air responsible for degradation of fullerenes is ozone. The destruction of C[sub 60] in toluene proceeds at least 5 orders of magnitude faster with O[sub 3] than it does with O[sub 2]. Ozonation of C[sub 60] in toluene resulted in the formation of C[sub 60]O, C[sub 60]O[sub 2], and C[sub 60]O[sub 3]. Oxides were not formed when crystalline C[sub 60] was exposed to O[sub 3]. C[sub 60]O was destroyed when heated in ambient air. The long-term survival of C[sub 60] in nature seems to require an environment low in O[sub 3].
