Abstract

Photophysical properties and reactivities of water-soluble micelle-like C₆₀ derivative, C₆₀((CH₂)₄SO₃Na)₆ (abbreviated as FC₄S), at the excited triplet state were investigated using laser flash photolysis. A new transient absorption band appearing at ca. 700 nm was attributed to the triplet-triplet (T-T) absorption band of FC₄S. This absorption was quenched by O₂ via energy transfer forming singlet oxygen, which was confirmed by its luminescence emission band; the quantum yield was evaluated to be 0.36.
