摘要
以乙醇为溶剂合成了脱氢枞胺水杨醛Sch iff碱(a)以及脱氢枞胺(5-硝基)水杨醛Sch iff碱(b),IR光谱确证其结构,用紫外-可见吸收光谱研究了它们在有机溶剂中的光致变色及溶致变色性能。研究发现,a和b在氯仿溶液中都能发生光致变色现象,b在二甲基甲酰胺(DMF)溶液中发生溶致变色现象,讨论了两种物质发生变色现象的机理。
Dehydroabietylamine salicylidene Schiff base (a) and dehydroabietylamine 5-nitrylsalicylidene Schiff base (b) were prepared in ethanol solvent. Their structures were characterized by IR spectroscopy. Their photochromic and solvatochromic properties in organic solvents were studied by UV-Vis spectroscopy. It has been found that: both a and b exhibited photochromism in chloroform solution. Base b exhibited solvatochromism in DMF solution. The mechanisms of photochromism and solvachromism of these two compounds were discussed.
