| Abstract: | The photochemistry of nine water soluble thioxanthone photoinitiators was examined by UV absorption,fluorescence,phosphorescence and ESR techniques.Maximal absorption,extinction coefficients,fluorescence and phoshorescence quantum yields,ESR intensity were determined.The solvent effects on absorption and fluorescence as well as the relationship between structure and photochemical activities were discussed. |
