“…Another type of fullerene adduct that has been utilized as a sensitizer for singlet oxygen generation includes the fullerodendrimer (199). The solubility in a large variety of solvents makes this compound suitable for sensitized oxidations.…”

This review article refers to the discovery of excited molecular oxygen, in particular on its lower singlet excited state ( 1 D g , 1 O 2 ). After a short report on singlet oxygen generation, the review is focused on the chemistry of this reactive species. Specifically, the three major reactions of 1 O 2 with unsaturated organic substrates, namely the [4 + 2] and [2 +2] cycloadditions as well as the ene reaction, are reviewed. The proposed mechanisms of these reactions, through the years, based on experimental and computational work, have been presented. Selected examples of singlet oxygen-synthetic applications are also mentioned. The [60]fullerene and fullereno-materials photosensitized oxidations in homogeneous, as well as in heterogeneous conditions, are also comprehensively discussed.Finally, the self-sensitized photooxidation of open cage fullerenes as well as fullerenes bearing oxidizable groups is reported.
