菁染料是一种良好的光谱增感剂,在其结构中引入冠醚因子可以提高感光度和增加稳定性,自1982年起,我们相继合成了含冠醚的苯非噻唑、苯并咪唑、与苯并硒唑菁染料。本文报道含冠醚苯并恶唑菁染料及半菁染料的合成,我们采用了一种简便的方法合成了关键的中间体—2—甲基6,7—二羟基苯并恶
Cyanine dye is a good spectral sensitizer. The introduction of crown ether factor in its structure can improve the sensitivity and increase the stability. Since 1982, we have successively synthesized phenothiazole, benzimidazole, And benzoselenazole cyanine dye. This paper reports the synthesis of crown ether benzoxazoline dyes and hemicyanine dyes, we used a simple method to synthesize the key intermediates 2-methyl 6,7-dihydroxybenzoic
