| 摘 要： | 本文合成了4个异硫氰基联苯乙炔类液晶化合物。通过1 HNMR、13 CNMR、19 FNMR、IR和MS谱图鉴定结构正确。用差示扫描热议(DSC)和偏光显微镜(POM)对化合物的相变温度进行了测试,发现所合成目标化合物均呈现向列相,其相变态温度范围在105~137℃,其双折射率高于0.47,可作为液晶光栅高双折射率液晶材料的有效组分。 |
| 关 键 词： | 异硫氰基 含氟联苯乙炔 高双折射率液晶 合成 |

| Abstract: | This paper has synthesized four isothiocyanato-diphenyl acetylene liquid crystal compounds.Their structures were identified by IR,1HNMR,13CNMR,19FNMR,MS spectra.Their phase transition temperatures were tested by using differential scanning calorimetric(DSC) and polarizing optical microscopy(POM).It is found that all of the new compounds show nematic phase,and their phase transformation temperature was in the range of 105℃ to 137℃.Their birefringence are more than 0.47,which can be used as the effective components of high birefringence liquid crystal materials of liquid crystal raster. |
| Keywords: | isothiocyanato fluorinated biphenyl acetylene high birefringence liquid crystal synthesis |
