摘　　要：论文以对酸敏感的罗丹明B为示踪剂,通过采用分光光度法和荧光光谱法,建立了光生酸剂在溶剂中和在高分子薄膜中光分解行为的评价方法。研究结果表明,本研究提出的光生酸剂在溶液中和在高分子薄膜中产酸效率的评价方法切实可行,能够准确地定量评价光生酸剂的光化学反应和产酸行为,用这种测量方法可以评价现有的三嗪类与硫鎓盐类光生酸剂的产酸优劣。A method for evaluating the photolysis behavior of photoacid generator in solvent and high polymer film has been established through spectrophotometry and fluorospectrophotometry by using the acid-sensitive Rhodamine B as tracer. Results showed that this method is feasible and practicable for evaluating the acid generating efficiency of photoacid generator in solution or high polymer film, yielding quantitatively precise data of the photochemical reaction and acid generating behavior, thus is very useful for evaluating the quality of different types of photacid generators e.g. triazines, sulfonium salts etc.
