Fullerenes and dihydrofullerenes as photodynamic sensitizers
- Univ. of California, Los Angeles, CA (United States); and others
Fullerenes C{sub 60} and C{sub 70} are excellent photosensitizers for the production of singlet oxygen. Their properties are particularly favorable since they are unusually photostable and neither quench nor react with singlet oxygen significantly themselves; in addition, they are only extremely weakly fluorescent, which makes them particularly useful for photophysical studies. The dihydrofullerenes, which have two sp{sup 3} carbons and various functionalities attached to the fullerene molecule, have much improved solubilities in polar media and photophysical properties (triplet energy and yield, singlet oxygen yield, oxidizing properties) that are quite similar to those of the fullerenes in many cases. A number of examples will be presented and some novel synthetic reactions described.
