中文摘要：

设计合成了两种含香豆素功能团的苄叉环戊酮光敏染料，用紫外．可见光谱、荧光光谱和光聚合实验研究了它们的光物理与光化学性质．结果表明与常用的高效光敏染料二-2.5-对二甲胺基苄叉环戊酮（BDMA）相比，两种新染料的吸收峰与荧光发射峰都大幅度红移，无论是在溶剂中还是在预聚物薄膜中它们的吸收光谱都能与Ar^＋激光器和绿光固体激光器很好的匹配；与常用的光引发剂4，4’-二甲基苯基碘盐（Omincat820）组合，两种新染料都表现出比BDMA更好的光敏性能，在可见光光敏引发聚合体系中具有很好的应用前景。

英文摘要：

Two novel benzylidene cyclopentanone photosensitizers containing coumarin moiety were synthesized. lnelr photophysical and photochemical properties were investigated using UV-vis spectra, fluorescence spectra and photopolymerization experiments. The results showed that compared to the common used high efficient photosensitizer 2,5-bis-[4-（dimethyl amino）-benzylidene]-cyclopentanone （BDMA） these two new dyes presented red-shift absorption and emission peaks, can match with Ar^＋ laser and 532 nm solid laser very well in solutions and resin films. Combined with commercial photoinitiator 4,4＇-dimethyl diphenyliodinium hexafluorophosphate （Omnicat820）, both of two dyes exhibited higher sensitizing photopolymerization efficiency than BDMA, which guaranteed their potential application in visible light photopolymerization.
