Novel tris-azo dyes and a liquid crystal composition containing the tris-azo dyes. The tris-azo dyes are of the general formula:
wherein R, and R2 are various aromatic groups including aromatic amines, substituted aromatic amines, hydroxy-substituted aromatic groups and substituted hydroxy- containing aromatic groups. When the tris-azo dichroic dyes are used as a guest dye in a host liquid crystal material, they form a novel liquid crystal composition for use in liquid crystal displays.
新型三偶氮染料和含有该三偶氮染料的液晶组合物。三偶氮染料的通式如下
其中 R 和 R2 是各种芳香基团,包括芳香胺、取代的芳香胺、羟基取代的芳香基团和取代的含羟基的芳香基团。当三偶氮二色性染料用作主液晶材料中的客体染料时,它们会形成一种用于液晶显示器的新型液晶组合物。
