| Abstract: | The photophysical and singlet oxygen generation studies of a few water-soluble triazatriangulenium cations (TATA) are reported. The photophysical studies include absorption spectrum, fluorescence spectrum, fluorescence quantum yield, fluorescence lifetime, triplet life time, triplet quantum yield and phosphorescence spectrum. The singlet and triplet energy levels of the compounds were determined. The triplet state properties have been characterized using nanosecond laser flash photolysis studies. The singlet oxygen generation has been estimated using chemical actinometry using disodium-9,10-anthracenedipropionic acid in water and 1,3-diphenylisobenzofuran in acetonitrile as the chemical actinometers and rose bengal was used as reference. |
