Abstract： |
The present invention is 3,4-difluoro-2-methoxyl biphenyl derivative in the given structure and its preparation process and application. The compound of the present invention has methoxyl radical, possessing small space size, small electric dipole moment and average dipole direction in the molecular major axis direction, introduced to the side of the biphenyl ring, so as to have great dielectric anisotropy in the molecular major axis direction, lowered smelting point and increased dissolvability. The compound of the present invention may find wide application in LCD, especially in TFT-LCD. |
