Liquid crystal compositions containing pleochroic dye |
摘要 |
Liquid crystal compositions containing pleochroic dyes. The pleochroic dyes are substituted anthraquinone dyes containing at least one carbocyclic or heterocyclic group linked to the anthraquinone moiety through a sulfur atom. The dyes are used in guest-host combinations with nematic liquid crystal compositions having positive dielectric anisotropy. Electro-optic devices containing these guest-host combinations are disclosed.
