characterized by spectroscopic methods (1H NMR, 13C NMR, HRMS, and single-crystal X-ray diffraction). The structural features of compound 2, 4, 5 and 6 were analyzed through the packing diagrams. The results indicated that the skeleton of all the molecules fused an oxazine ring to an indoline fragment in near-orthogonal arrangement. Furthermore, the 3D supermolecular frameworks were formed by the hydrogen
摘要 成功合成了一系列新型螺恶嗪衍生物,并通过光谱方法(1H NMR、13C NMR、HRMS和单晶X射线衍射)对其进行了表征。通过堆积图分析了化合物2、4、5和6的结构特征。结果表明,所有分子的骨架都以近正交排列的方式将一个恶嗪环与一个二氢吲哚片段融合在一起。此外,3D 超分子框架是由氢键和范德华相互作用形成的。此外,已在各种介质中对合成化合物的光致变色行为进行了详细研究:有机溶剂、聚(甲基丙烯酸甲酯)和聚(乙烯醇缩丁醛)基质(PMMA、PVB)。
