一种含有二氟甲氧基桥键的液晶化合物、组合物及其应用
摘要：
本发明涉及一种含有二氟甲氧基桥键的液晶化合物，该液晶化合物具有如下结构通式I：所述结构通式I中，R1表示‑H或具有1～12个碳原子的烷基或烷氧基；R2表示‑F，‑Cl，‑CN，‑NCS，‑CF3，‑OCF3，‑OCF2Cl或具有1～12个碳原子的烷基或烷氧基；L1、L2、L3和L4各自独立地表示‑H或‑F。本发明还涉及含有所述液晶化合物的组合物。本发明进一步涉及所述液晶化合物以及组合物在液晶显示领域的应用。本发明提供的液晶化合物以及组合物具有优异的介电各向异性，可以显著降低液晶显示装置的驱动电压，具有良好的应用前景。
摘要（英）：

The invention relates to a liquid crystal compound containing a difluoromethoxy bridge bond. The liquid crystal compound has a structural general formula shown as the specification, wherein R1 represents -H or alkyl or alkoxy having 1-12 carbon atoms; R2 represents -F, -Cl, -CN, -NCS, -CF3, -OCF3, -OCF2Cl or alkyl or alkoxy having 1-12 carbon atoms; L1, L2, L3 and L4 independently represent -H or -F. The invention also relates to a composition containing the liquid crystal compound. The invention further relates to application of the liquid crystal compound and the composition in the liquid crystal display field. The liquid crystal compound and the composition provided by the invention have excellent dielectric anisotropy, can significantly lower the driving voltage of a liquid crystal display device, and have good application prospects.
