摘　　要：以方酸和N,N-二丁基苯胺为原料,分别采用两步法合成了2种硫代方酸菁染料.用硅胶柱层析法分别对合成染料进行分离提纯,并通过核磁共振氢谱对产品结构进行了表征,测试了产品的基本光谱性能,结果证明两种菁染料均具有良好的光学性能.Two squaraine dyes based on squaric acid and N, N-dibutylaniline are synthesized in two steps （condensation and sulfidation）. And the crude products are purified by column chroma- tography （ silica gel）. The chemical structures of the target compounds and key intermediate pro- ducts are well confirmed by 1H NMR. The spectral properties of the target compounds are also in- vestigated by UV-vis absorption spectroscopy.
