The photoswitching properties of two easily synthesized isatin 4-nitrophenylhydrazones were investigated. Although the parent isatin 4-nitrophenylhydrazones exhibit low addressability which hampers their photochromic applications, the addition of strongly basic anions to phenylhydrazone solutions creates a new Vis–Vis photochromic system with the unusual azo/azine-to-hydrazone photo-tautomerization
研究了两种容易合成的靛红4-硝基苯腙的光开关特性。尽管母体靛红 4-硝基苯腙表现出低可寻址性,这阻碍了它们的光致变色应用,但向苯腙溶液中添加强碱性阴离子会产生一种新的 Vis-Vis 光致变色系统,该系统具有不寻常的偶氮/吖嗪到腙光互变异构过程作为光开关机制。据我们所知,这是与阴离子辅助偶氮/吖嗪-腙光互变异构有关的第一份报告。
