新型含三嗪环希夫碱大环化合物的合成及其离子识别研究

Synthesis and Ion Recognition of Novel Schiff Base Macrocyclic Compounds Containing Thiotriazinone

摘要:

以三聚氯氰、二乙胺、对硝基酚、1,2-二溴乙烷、水杨醛、对羟基苯甲醛、香草醛和异香草醛为原料，采用高度稀释法合成了一类新型的含三嗪环的席夫碱大环化合物，并通过IR、1H NMR和ESI/MS对其结构进行了表征。紫外光谱研究表明，席夫碱大环5对Fe3+离子有专一性识别作用。

Abstract:

Several novel Schiff base macrocyclic compounds of Thiotriazinone were synthesized from cyanuric chloride, diethylamine p-nitrophenol, 1,2-dibromoethane, salicylaldehyde, p-hydroxybenzaldehyde, vanillin and isovanillin by high dilution method, and their structures were characterized by IR, 1H NMR and ESI/MS techniques. The studies on the UV-Vis absorption spectroscopies show that Schiff base 5 have a selective recognition for Fe3+.
