设计并合成了２，６二苯基－ｐ－苯醌－４－氯亚胺１ｃ，作为一个新的使酚类显色的Ｇｉｂｂｓ试剂，与酚类在碱性溶液中生成兰绿色的２，６－二苯基靛酚盐２ｃ。由于苯基的引入，扩大了靛酚的共轭体系和极化效应，故２，６＝二苯基靛酚盐２ｃ的λ＿（ｍａｘ）和ε＿（ｍａｘ）都比相当的２，６－二氯靛酚盐２ａ为大。２ｃ经酸化后成为红色的游离２，６－二苯基靛酚，具有良好的化学稳定性。 The 2,6-diphenyl-p-benzoquinone-4-chloroimine 1c has been designed and synthesized as a new Gibbs reagent for the color development of phenolic compounds, producing green-blue 2 with phenols in alkaline solution, 6-diphenyl indophenol salt 2c. Due to the introduction of phenyl groups, the conjugated system of indophenol and the polarization effect are enlarged. Therefore, the λ max and ε max of 2,6 = diphenylindophenolate 2c are all higher than those of 2,6- Chloroindophenolate 2a is large. 2c acidified into a red free 2,6-diphenylindophenol, has good chemical stability.
