The quenching of excited singlet and triplet states of zinc phthalocyanine was studied in DMSO and in mixed micelles containing the functional surfactant as one and cationic cetyl trimethylam- monium bromide(CTAB),anionic sodium dodecylsulfate(SDS)and neutral TX-100 surfactant as the other component.Fluorescence quenching and laser photolysis studies indicate that the functional surfactants are solubilized at different sites in micelles,the process depends on chain length and exerts great influence on the quenching of zinc phthalocyanine excited states.展开更多

文摘A series of functional surfactants of N-alkyl-N'-butyl viologens has been synthesized. The quenching of excited singlet and triplet states of zinc phthalocyanine was studied in DMSO and in mixed micelles containing the functional surfactant as one and cationic cetyl trimethylam- monium bromide(CTAB),anionic sodium dodecylsulfate(SDS)and neutral TX-100 surfactant as the other component.Fluorescence quenching and laser photolysis studies indicate that the functional surfactants are solubilized at different sites in micelles,the process depends on chain length and exerts great influence on the quenching of zinc phthalocyanine excited states.
