| 摘 要： | 合成了双水杨醛缩对苯二胺（L1）及其与锌（Ⅱ）的配合物（L1Zn）和双水杨醛缩间苯二胺（L2）及其与镍（Ⅱ）的配合物（L2Ni），利用核磁共振、红外光谱、紫外-可见光谱、荧光光谱和质谱对4种物质的结构和性质进行了表征。结果表明：两种Schiff碱化合物经二价金属离子配位后其荧光光谱均发生了蓝移现象;热激发实验发现L1Zn具有可逆热致变色性质，而L2Ni热致变色不可逆，表明它们是一类新型有机热致变色材料。 |

| Abstract: | Zinc (Ⅱ) complex (L1Zn) derived from Schiff base of bis-(salicylaldehyde)-p-phenylenediamine (L1) and nickel (Ⅱ) complex (L2Ni) derived from Schiff base bis-(salicylaldehyde)-m-phenylenediamine (L2) were prepared, and their structures and properties were characterized by nuclear magnetic resonance, infra-red spectroscopy, ultraviolet spectroscopy, fluorescence spectroscopy and mass spectroscopy.The results showed that the fluorescence spectroscopy of two Schiff base bivalent ion complexes indicated blue shift compared with corresponding salicylaldehyde-derived Schiff base.Moreover, thermal excitation experimental results indicated that L1Zn and L2Ni were reversible and irreversible thermochromism respectively, and that they were new species of organic thermochromic materials. |
| Keywords: | Schiff base complex fluorescence reversible/irreversible thermochromism |
