The Quenching of Singlet Oxygen

The kinetics and mechanisms of processes involving the quenching of oxygen in the singlet state (¹Δ_g) are examined. The rate constants for the deactivation of singlet oxygen in various solvents, for the reactions of singlet oxygen with unsaturated and aromatic compounds, and for processes involving the quenching of singlet oxygen by amines, metal complexes, and certain other compounds have been compiled. The influence of the polymer matrix on the reactivity of electron acceptors and the efficiency of quenching agents is considered and the role of singlet oxygen in photochemical oxidation reactions of low- and high-molecular-weight organic compounds is discussed.
