摘　　要：本文对８种水溶性硫杂蒽酮类光引发剂进行了紫外可见光谱、荧光光谱以及电子自旋共振光谱（ＥＳＲ）等测试．测定了最大吸收波长，计算了摩尔消光系数，荧光量子产率，测定了ＥＳＲ信号强度等．he photochemical properties of eight novel watersoluble thioxanthone photoinitiators were studied by UV absorption, fluorescence and ESR. The maximal UV absorption wavelength and extinction coefficient, fluorescence quantum yield and the signal intensity of ESR were determined. The relationship between the structure and the photochemical properties was also discussed.\=
