【摘要】 运用示差扫描量热仪、偏光显微镜、X射线衍射仪和计算机模拟分子链处于能量最低、最优构象时的分子长度等手段,对新合成的4-(6-羟基己氧基)联苯-4′-甲酸-L-2甲基丁醇酯进行表征。结果表明:该液晶化合物为近晶A相。合成总收率为47.3%(相对于4-羟基-4′-氰基联苯)。更多还原

【Abstract】 L-2-methyl butyl 4-[(6-hydroxylhexyl)oxy] biphenyl-4′-carbonylate were characterized by means of DSC, POM, XRD and computer simulating molecular chain length in lowest energy and optimum structure. The result shows that target molecule is smectic A phase with a total yield of 44.1 %(based on 4-hydroxyl-4′-cyanobiphenyl).更多还原
