Liquid crystal compositions and devices and novel compounds |
摘要 |
There are described novel perylene dyes which have at least one, and preferably two, substituted twisted biphenylene radicals. The substituted biphenylene radicals include substituents which confer a non-coplanar molecular configuration about the long axis of the dye molecule. The dyes are soluble in various liquid crystal materials and exhibit a high order parameter in solutions of liquid crystal material. Also disclosed are liquid crystal compositions and liquid crystal devices.
