摘　　要：以对甲氧基苯乙酮、萘乙酮生色团为母体、杂环叔胺三亚乙基二胺,吡啶,3-甲基吡啶和四苯硼盐为原料,合成了6种四苯硼季铵盐光产碱剂。考察了其荧光光谱特性,发现甲氧基苯甲酰亚甲基光产碱剂的荧光量子效率较低,而萘甲酰亚甲基光产碱剂较高。利用稳态光解法研究了其不同条件下的光解动力学,符合一级反应。Six Quaternary Ammonium tetraphenyl borates salt photobase generators were synthesized with the use of p-methoxy phenacylmethylene or 2-naphthoymethylene as chromophore, and triethylene diamine, pyridine or 3-methyl pyridine as tertiary amine. Their fluorescence emission properties were studied and their photolysis kinetics was investigated in different media by means of steady state photolysis method. The results show that their photolysis kinetics follows the first order reaction.
