摘要
以对羟基联苯腈为原料,合成了一系列的具有较长烷氧取代基的4-氰基联苯醚类液晶材料。利用FTIR、1H NMR对这类液晶材料进行了结构表征,通过差示扫描量热法(DSC)、偏光显微镜(POM)研究了材料的液晶性能。初步探讨了柔性端基长度与烷氧基联苯类液晶材料的液晶性能的关系。
The synthesis of a series of 4＇-alykyloxy-4-carbonitrle biphenyl liquid crystals was synthesized from 4-hydroxybiphenyl-4＇-carbonitrle. The structure characterization of the compound by FIIR, ^1 H NMR. Besides, the thermotropic liquid crystalline properties of the products were characterized by DSC, POM. The influences of structure and the flexible chain length on liquid crystalline properties were studied initially.
