Abstract:

Deactivation of zinc dicarboxydiamide phthalocyanine (ZnPc) by quinones was investigated in hexadecyltrimethylammonium chloride micelles by fluorescence and triplet quenching experiments. Fluorescence data were handled according to the method of Encinas and Lissi (Chem. Phys. Lett., 91 (1982) 55) to derive quencher partition constants. The same data were used to obtain singlet quenching constants. Triplet quenching and quencher exit rate constants were obtained by steady state singlet oxygen phosphorescence detection. The correlation of the quenching rate constants with the redox potentials indicates electron transfer quenching. © 1994.
