2,6-双(对氨基苯基偶氮)-9,10-蒽二酮的合成

Synthesis of 2,6-Bis(p-aminophenylazo)-9,10-anthracenedione

从2,6-二氨基蒽醌出发,经亚硝酰硫酸双重氮化,再与苯胺偶合合成了未见文献报道的三阶有机非线性光学材料———2,6-双(对氨基苯基偶氮)-9,10-蒽二酮,收率56.8%。其结构经1H NMR,IR和元素分析确证。

A new third-order nonlinear optical organic material, 2,6-bis （p-aminophenylazo）-9,10-anthracenedione, was synthesized by bisdiazotizing of 2,6-diaminoanthraquinone with nitrosylsulfuric acid and then coupling with aniline. The yield was 56.8%. Its structure was confirmed by ^1H NMR, IR and elemental analysis.
