摘要: 本工作对几种新型硫杂蒽酮化合物敏化光解重氮盐问题进行了研究。工作表明:敏化反应是通过电子转移过程实现的,重氮盐所带取代基以及溶剂对重氮盐的光解有较大影响。十分有趣的是该体系对甲基丙烯酸甲酯进行光敏自由基引发聚合的速率和其光解反应速率有很大的不同,本文对此现象进行了讨论。

Abstract: The sensitized photolysis of diazonium salts by several new thioxanthone compounds has been investigated in this work. Results indicated that the sensitized reaction was realized by the route of electron-transfer. The substituents in diazonium salts and the solvent used possess important effect on the photolysis of diazonium salts. It is interesting to find that the rate of photo-polymerization of MMA initiated by this system was different from the rate of photolysis. This phenomenon was discussed briefly.

Key words: Diazonium salt, Sensitized photolysis, Thioxanthone, Photo-polymerization, Electron-transfer
