摘要：合成了一种水溶性螺噁嗪三苯基膦盐化合物1,并由1HNMR、MS和元素分析表征确认了结构。UV-Vis吸收光谱研究表明,该化合物在有机溶剂中表现出与其它螺噁嗪类化合物类似的光致变色性质,并在含水乙醇溶液中表现出对pH敏感的光照显色效应,即:依赖于pH光诱导开环体呈现出两种结构稳定态,调节pH可实现这两种结构稳定态的相互转换。
A water-soluble spirooxazine functionalized with triphenylphosohonium bromide was synthesized.Its structure was determined by 1 H NMR,MS and elemental analysis.The photochromic properties of the compound in various solvents were also studied.The results indicated that the as-synthesized spirooxazine exhibited similar photochromic behavior to other spirooxazines in aprotic solvents,and the pH-sensitive photochromism was observed in alcohol /water solution,in which the photo-induced open form presents two stable structures and their inter-conversion strongly depends on pH of the solution.
