不对称功能性吲哚三甲川菁染料的合成及光谱

以苯肼盐酸盐为原料,将其与甲基异丙基酮通过闭环反应,生成2,3,3-三甲基吲哚的衍生物,再经过与溴乙烷、六溴己酸反应成吲哚盐,然后和二甲脒反应得到吲哚乙烯基苯胺,最后合成了两种不同取代基团的水溶性的不对称三甲川吲哚菁染料,并通过核磁、质谱等测试手段对其结构进行表征.研究了该染料的紫外吸收光谱和荧光光谱.

Synthesis and Spectra of Functional Unsymmetrial Trimethine Cyanine Dyes

The 2,3,3-trimethyl indole derivatives were synthesized by closed-loop reaction from phenylhydrazine derivatives and methyl isopropyl ketone.Then the 2,3,3-trimethyl indole derivatives were alkylated by ethyl bromide,6-bromhexine acid to afford indole salts,which then were reacted with N,N＇-diphenylformamidine to get indole ethylene aniline.At last,the unsymmetrical water soluble cyanine dyes with two different functional groups were synthesized.The structures of the dyes were characterized by 1HNMR,MS.The UV absorption and fluorescence spectra of the dyes were also studied.
