摘要: 设计并合成了一类新型的对三氟甲氧基肉桂酸酯类液晶,其相变行为通过DSC及偏光显微镜进行了观察和测试. 化合物A呈现多种相态。而化台物B引入了四氟亚苯基.其相态数量减少、相变温度发生较大的变化。
英文摘要: Two series of 4-trifluoromethoxycinnamate liquid crystals were synthesized. Their phase transition temperatures were measured and confirmed by a polarization microscope and a DSC, respectively. The mesomorphic properties and fluorosubstituent effect were studied in detail, and the compounds A exhibit smectic A, smectic B and nematic phases. When 2,3,5,6-tetrafluorophenyl groups are introduced into compounds B, the smectic B phase disappears and the transition temperatures are changed in large.
