摘要: 合成了中心桥键为酯基和Schiff碱基连接且分子中含4个苯环的17个化合物,其中有带支链和不带支链的化合物,化合物的结构通过IR,NMR和元素分析进行表征,其介晶性通过DSC和偏光显微镜进行研究.讨论了取代基对介晶性的影响.结果表明,该类型结构的二茂铁化合物绝大多数具有液晶性,取代基对介晶性的影响较小.

关键词: 液晶, 金属有机化合物, 二茂铁, 末端基团

Abstract: Seventeen ferrocene-containing compounds with four phenyl rings and ester, imine group as the central bridge were synthesized. The structures were characterized by IR, NMR and elemental analysis. The mesogenic properties were studied by DSC and polarized optical microscopy. The effect of substituents on the mesogenic behavior was discussed. The results show that most of these compounds have a liquid crystal phase.

Key words: Liquid crystal, Organometallics, Ferrocene, End group
