文档介绍：三嗪衍生物的合成及应用
摘要
本文通过利用三嗪衍生物2,4-二-(2-噻吩乙烯基)-6-(4′-N,N-二甲氨基苯乙烯基)-1,3,5-均三嗪与金属离子Fe3+ 络合,形成主体-Fe3+ 络合物,通过在紫外光谱中实时测得响应曲线,然后由于不同阴离子的络合常数不同,加入各种阴离子如四丁基磷酸二氢铵,四丁基***化铵,四丁基***化铵,四丁基溴化铵,四丁基碘化铵,四丁基醋酸铵,四丁基硫酸铵和***化四丁基***八种不同的阴离子,通过观察紫外光谱图的变化,来进行针对以上阴离子的特异性检测。由于以上八种不同的阴离子有可能存在和络合物存在竞争配位或者协同配位的情况,可以把Fe3+ 从络合物中置换出来,形成新的Fe3+ 络合物,从而在紫外光谱中表现出特异性、比例性变化。利用紫外光谱初步探讨在三嗪衍生物2,4-二-(2-噻吩乙烯基)-6-(4′-N,N-二甲氨基苯乙烯基)-1,3,5-均三嗪和Fe3+ 在阴离子识别中的作用机理。

Triazine derivatives Synthesis and Application
Abstract
We synthesized pound plex the thiophene ring named 2,4 - II - (2 - thienyl ethenyl) -6 - (4'-N, N-dimethylamino) styryl] -1,3,5 - triazine Vinyl thiophene with Fe3+. By the means of UV spectra, we get the Response curve. While the difference plexation constants in difference anion, when add in the several anions such as Tetrabutyl ammonium dihydrogen phosphate,Tetrabutylammonium chloride Tetrabutylammonium fluorideTetrabutylammonium bromide, Tetrabutylammonium iodide,Tetrabutylammonium acetate,Tetrabutyl ammonium sulfate,Tetrabutylamm-onium cyanide. We can have the specific detection of anions. But in case of the May exist and the presence petitive ligand or co-plex,it can replace the thiophene ring and form a pound, panied by the change in UV spectrum .Preliminary studied mechanism of the Thiophene ring derivative 2,4 - II - (2 - thienyl ethenyl) -6 - (4'-N, N-dimethylamino) styryl] -1,3,5 - triazine Vinyl thiophene and Fe3+ in the area of anion recognition.
Key words : Anion sensors; Collaborative coordination; Competitive ligand; Fe3+ ; UV spectrum
