本文研究了酸碱度和不同胺类给电子体对噻嗪类染料在固态基质中光退色反应的影响.发现当染料激发三线态的质子化形式含量与给电子体有效还原形式的含量最优配合时可获得最佳的光氧化还原效果.对胺类给电子体,如其氮原子周围有供电子基或能与染料缔合的化合物参加光反应时则还原效果较好.
In this paper, the effects of pH value and different amine-based electron donors on the photorefractive reaction of thiazine dyestuffs in a solid matrix were investigated. It was found that when the protonated form of the excited triplet state and the effective reduced form of the electron donor Can obtain the best photo-oxidation reduction effect.For the amine electron donor, such as its nitrogen atoms around the electron donating group or can associate with the dye compound to participate in the photoreaction, then the reduction effect is better.
