摘要

设计并合成了4个双环己基含氟二苯乙炔类负性液晶化合物。4个化合物的相变研究是通过偏光显微镜和差示扫描量热仪检测的。合成的液晶化合物都具有高双折射率，低黏度及高达270℃的清亮点，只有向列相的液晶化合物可以用来制备性能良好的高双折射率混合物液晶，也可用于自适应光学系统空间光调制器。4个目标化合物是通过sonogashira交叉偶联反应得到的。

Abstract

Four fluorinated diphenyl acetylene negative liquid crystal compounds containing dicyclohexyl were designed and synthesized. Target liquid crystal compounds were measured by polarised optical microscopy and differential scanning calorimetry and their good mesomorphic properties were obtained. The target compounds obtained high birfringence

low rotational viscosity and high clearing point about 270℃. The nematic liquid crystals could satisfy the requirements of a high temperature component in TFT-LCD

it also could be used in adaptive system like as application in construction of spatial light modulator. Four target compounds were synthesized by sonogashira coupling reaction.
