摘要：本文用紫外吸收光谱、荧光光谱、磷光光谱、电子自旋共振光谱对九种水溶性硫杂蒽酮类光引发剂的光化学行为进行了研究 ,计算了摩尔消光系数、荧光量子产率、磷光量子产率 ,同时测定了溶剂效应对紫外、荧光光谱的影响 。
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.
