different aromatic amines gave a series of symmetrical diarylethenes containing Schiff-base moieties, which were reduced with NaBH4 to give the corresponding diarylethene amines. The structures of all new compounds were confirmed by NMR spectroscopy, mass spectrometry, X-ray diffraction and elemental analysis. Their photochromic properties were also investigated, revealing that diarylethene imines displayed
将二醛1与不同的芳族胺缩合,得到一系列含有席夫碱基团的对称二芳烃,并用NaBH 4还原得到相应的二芳基乙烯胺。所有新化合物的结构均通过NMR光谱,质谱,X射线衍射和元素分析确定。还研究了它们的光致变色性质,发现二芳基亚乙基亚胺在溶液中显示出比其胺类似物更好的光致变色性质。此外,我们发现,通过改变芳族胺前体,可以获得具有不同多色行为的二芳烃。研究了许多不同的芳香胺,包括不同的碳骨架和在不同位置的不同卤素取代基,以调节多色行为。
