Abstract

The quantum yields of photolysis (Φ_p) of C₆₀,C₇₀,C₇₆, and C₈₄ dissolved in tetrachloroethylene, and irradiated by visible cw Ar⁺ laser radiation were determined and compared. We found that Φ_p(C₆₀)>Φ_p(C ₇₀)>Φ_p(C₇₆)>Φ_p(C ₈₄). The high photostability of C₈₄ under the given irradiation conditions is discussed in terms of the particular physical and chemical properties of this fullerene cage. The quantum yields of singlet oxygen production (Φ_Δ) photosensitized by C₇₀,C₇₆, and C₈₄ were determined. Their values are correlated with the observed photodecomposition yields.
