摘要
传统光敏剂是小分子的多环芳烃类如蒽、芘、苝等,其中多数光敏剂都是通过电子转移来增感阳离子引发剂,增感效果很好,但这类光敏剂存在着溶解性差,蒸汽压高,有毒性的缺陷。目前采用的改进方法主要是制备其衍生物或将其制备成聚合物,即高分子光敏剂。
Traditional photosensitizers are small molecules of polycyclic aromatic hydrocar- bons, such as anthracene, pyrene, perylene,etc. The photosensitive mechanism of electron transfer is commonly accepted. Although the sensitizing effect of such photosensitizers are good, there are three defects, poor compatibility , high vapor pressure, toxic . The improved methods currently used are preparing the derivatives and preparing the polymer or eopolymer.
