摘要: | 本論文合成了數個系列的含氟乙炔及雙乙炔液晶化合物,除了熱力學性質 之外,並測其介電異向性及雙折射率,所合成之化合物可應用於液晶顯示 元件上。 Several series of new fluorinated tolane and diacetylene liquid crystals are synthesized. Their phase transitions as well as physical properties, e.g. dielectric anisotropy and birefringence are measured. These compounds which exhibit a high resistivity,high birefringence, low viscosity and low threshold voltage are useful in display application. |
