稠环化合物敏化硫鎓盐引发阳离子光聚合的研究

The Study of Cationic Photopolymerization Initiated by Dye-Photoredox Sulfonium Salt

合成了三芳基硫六氟磷酸盐光引发剂。研究了不同稠环化合物对硫盐引发阳离子光聚合速度的影响,用光致电子转移(光氧化还原)理论解释了这些稠环化合物的光敏机理。

Triarylsulfonium fluorophosphate was synthesised. The effects of dyes were studied on cationic photopolymerizaton. The redox potentials of dyes were determined by oscillopolarography. The photoinduced electron transfer from excited state dyes to salt was described.
