摘要: 研究了Oxonol在不同溶剂中的吸收和荧光光谱,观察到反常的溶致变色行为.研究了由Oxonol和双 (三氯甲基)三腈化合物所组成体系在不同环境中的光诱导电子转移生酸反应和其褪色效应,发现这一体系可在红光照射下灵敏地引发某些预聚物而发生光交联反应.对Oxonol在胶束体系中的荧光发射进行了研究,比较了它们的荧光量子产率,并对出现这种现象的原因进行了初步讨论.

关键词: 光诱导电子转移, 光交联反应, 光生酸反应, Oxonol染料, 三腈类化合物

Abstract: The absorption and fluorescence spectra of Oxonol in different solvents were studied in this work.An abnormal solvatochromic phenomenon was observed.The photo-induced acid generation and photo fading effect of system composed of Oxonol and bis(trichloromethyl)triazine were studied.It was found that the system can initiate some prepolymers to crosslink under irradiation of red light effectively.In addition,the fluorescence emission and the fluorescence quantum yield of Oxonol in micellar system were also studied.The phenomenon observed was discussed preliminarily.

Key words: photoinduced electron transfer, photocrosslinking, photo-acid-generation, Oxonol dye, triazine compounds
