A liquid crystal compound and a liquid crystal medium are described. The liquid crystal compound is stable to heat and light and has a large dielectric anisotropy and a large optical anisotropy. The liquid crystal medium has a wide temperature range of liquid crystal phase, a large optical anisotropy and a large dielectric anisotropy, and exhibits an optically isotropic liquid crystal phase. The liquid crystal compound has 4 or 5 benzene rings, one of which is a chlorofluorobenzene ring. The liquid crystal medium is characterized in containing the liquid crystal compound and a chiral dopant and exhibiting an optically isotropic liquid crystal phase.
本文描述了一种液晶化合物和液晶介质。液晶化合物在热和光的作用下稳定,并具有大的介电各向异性和大的光学各向异性。液晶介质具有广泛的液晶相温度范围,大的光学各向异性和大的介电各向异性,并表现出光学各向同性液晶相。液晶化合物具有4或5个苯环,其中一个是氯氟苯环。液晶介质的特点在于含有液晶化合物和手性掺杂剂,并表现出光学各向同性液晶相。
