Abstract
The total quenching rate constants (sum of physical quenching and chemical reaction) of singlet oxygen 1O2 by various fullerenes (C60, C70, C76, C82, La@C82, Ce@C82, Ce2@C80) were determined. The 1O2 quenching capabilities of C82 and endohedral metallofullerenes are found to be comparable to that of β-carotene, a well-known strong 1O2 quencher. This remarkable 1O2 quenching by metallofullerenes is explicable in terms of a combination of energy and charge transfer processes.
