香草醛类Schiff碱及其配合物的合成、表征及性质

Synthesis.characterization and properties of vanillin Schiff bass and it's metal complexes

用固、液合成法合成邻联甲苯胺双缩香草醛(L1)和邻联甲苯胺单缩香草醛(L2)Schiff碱配体。L1分别与金属离子[M=Cu(Ⅱ)、Co(Ⅱ)、Ni(Ⅱ)]配合,合成3种新型配合物ML1。结构经UV-Vis、1H NMR、IR及元素分析对配体、配合物进行表征,结果表明合成物质与预期一致。它们具有良好的热致变色性和一定的荧光性。

Novel o-tolidine bis（L1）-and single（L2）-vanillin Schiff base ligand were synthesized by solid and liquid-phase method.Three novel Schiff base metal complexes,CuL1、CoL1and NiL1,were synthesized by reaction of L1with metal ion[Cu（Ⅱ）、Co（Ⅱ）、Ni（Ⅱ）],respectively.Their structures were characterized by UV-Vis,1H NMR,FT-IR and elemental analysis.The results showed that synthetic substances were same with the expectations.They have good thermochromic and fluorescence properties.
