spirooxazine derivatives containing nitrogen heterocycles have been synthesized and characterized by 1H NMR, 13C NMR, IR and HRMS in this paper, and the photochromic behaviors of the compounds have been studied in different solutions and the compounds were embedded into a poly(methylmethacrylate) and poly(vinyl butyral) matrix (PMMA, PVB). In solutions, they showed thermochromism and acidichromism. Embedded
本文合成了一系列新型的含氮杂环螺恶嗪衍生物,并通过1 H NMR,13 C NMR,IR和HRMS进行了表征,并研究了该化合物在不同溶液中的光致变色行为,并将其包埋在环烷中。聚(甲基丙烯酸甲酯)和聚乙烯醇缩丁醛基质(PMMA,PVB)。在溶液中,它们显示出热致变色和酸致变色。嵌入聚合物薄膜中,化合物热脱色的光致变色动力学发生了显着变化,发现脱色曲线符合双指数函数。详细研究表明,代表性化合物1 [1,3,3-三甲基-6'-哌啶子基-螺(吲哚啉-2,3'-[3 H]-喹啉基[2,1- b ] [1,4]恶嗪)在聚甲基丙烯酸甲酯和聚乙烯醇缩丁醛基体中表现出较高的抗疲劳性。
