Quenching of Singlet Oxygen by Cobalt Complexes

摘要: Certain coordination compounds are efficient quenchers of singlet (1Δg) oxygen (Wilkinson 1981), referred to firstly by Carlsson (1974). Afterwards experiments were aimed obtain a better insight into the polymer stabilizing efficiency these (Allen 1984). In spite results, however, no general theory emerged which could explain large differences in quenching ability various compounds. The only study substituent effect on ligands has not been evaluated kinetically (Kajitani 19 85). Therefore we undertook systematic compounds, starting with series cobalt complexes.
