摘　　要：合成了几种含2,6-二氟-异硫氰酸酯结构的单体液晶材料并进行性能评测,确定该材料具备较高的相变温度、较大的光学各向异性常数(0.150~0.400)和电学各向异性常数(25.0~45.0),并且具有很好的热稳定性和互溶性,单组分在混晶中占比超过10%~20%.In this paper, several monomer liquid crystal materials containing 2,6- two fluoro isothiocyanate were synthesized, and the properties of the material were evaluated. It was determined that the material has high phase transition temperature, large optical anisotropy constant (0.150~0.400),electrical anisotropy constant (25.0 ~45.0), good thermal stability and intersolubility. The proportion of single component in mixed crystal exceeds 10%~20%.
