Under illumination in organic solvents, pristine fullerenes, and reveal a high triplet state yield that is close to unity and are known to effectively generate electronically excited singlet oxygen We applied the ESR technique to monitor generation efficiency for both fullerenes in toluene solutions that were exposed to the white light. Total signal intensity of TEMPO, a stable nitroxide resulting from attack on ESR-silent precursor, TMP (2,2,4,4-Tetramethylpiperidine), was measured to follow the singlet oxygen generation. We also performed a similar experiment using a solid sample of paraffin. The relative efficiency of generation in the presence of both and in solutions and in a solid sample was estimated from the increase rates of TEMPO formation.
