【摘要】 合成了一种新型的苯并菲类盘状液晶,2-烯丙酯基-3,6,7,10,11-五戊氧基苯并菲。其化学结构由核磁共振氢谱和傅里叶红外确定,而其介晶性能由差示扫描量热法和偏光显微镜确定。表明该化合物在降温回冷时表现出一种典型的柱状相织构,它具有一个从室温到175℃宽的液晶温度范围。由于其侧链双键的不饱和性,为液晶高分子的分子设计和制备建立了基础。更多还原

【Abstract】 A novel tnphenylene-based discotic liquid crystal 2-aUylcarboxyl-3,6,7,10,11-penta pentyloxy-triphenylene was synthesized.The chemical structure was determined by IH-NMR and FT-IR spectrum,and its mesomorphism was investigated by Differential Scanning Calorimeter(DSC) and Polarizing Optical Microscopy(POM) method.The compound showed classical texture of columnar phase in a wide mesophase temperature from the room temperature to 175℃ during cooling.It also set the foundation of designing and preparing liquid crystal polymer due to its double bond of the side chain.更多还原
