  The present invention relates to a liquid crystal compound having a structure as shown by formula I, wherein R is selected from H and alkyl or alkoxy containing 1-12 carbon atoms in which one or more H are unsubstituted or substituted with halogens; A 1 , A 2 and A 3 are each independently selected from: a single bond, 1,4-cyclohexylene, 1,4-phenylene, wherein hydrogen in 1,4-phenylene may be each independently substituted with one or more halogens; and Z 1 and Z 2 are each independently selected from a single bond or —(CH 2 ) 2 —. The compound of the invention has the characteristics of low rotational viscosity, large dielectric anisotropy, good mutual solubility and stability. The driving voltage of a device can be remarkably reduced after the compound is added to a composition. Thus, the compound of the invention has prosperous applications in LCD industry.

  本发明涉及一种具有如公式I所示结构的液晶化合物，其中R从H和烷基或含有1-12个碳原子的烷氧基中选择，其中一个或多个H未取代或用卤素取代；A1、A2和A3分别独立选择自：单键，1,4-环己烯基，1,4-苯基，其中1,4-苯基中的氢原子可以各自独立地被一个或多个卤素取代；Z1和Z2各自独立选择自单键或—(CH2)2—。该发明的化合物具有低转动黏度、大介电各向异性、良好的互溶性和稳定性的特点。在将该化合物添加到组合物后，设备的驱动电压可以显著降低。因此，该发明的化合物在液晶显示行业有着广泛的应用前景。
