摘要
以五氟苯基三甲基硅乙炔为起始原料制备了一系列的4’-[(4-烷氧基-2,3,5,6-四氟苯基)乙炔基]苯甲酸4”-庚基苯酚酯的液晶化合物。进行了结构分析,确证其结构。偏光显微镜观察到的结构表明它们存在向列相以及近晶C相。
A homologous series of 4'-n- Heptylphenyl 4 "- C( 4- n- alkoxy- 2, 3, 5, 6- tetrafluorophenyl ) ethynyl]benzoates have been prepared from the starting material 1- pentafluorophenyl- 2-trimethylsUya-cetylene. Polarizing microscopic textural observation shows that they exhibit nematic phase or smectic C(Sc) phase.
