带端烯基席夫碱液晶化合物的合成与表征

Synthesis and characterization of Schiffbase liquid crystal compound with terminal vinyl group

通过取代、还原、加成等反应,合成了一种带端烯基的席夫碱液晶化合物4-烯丙氧基苯亚甲基(-4’-丁氧基)苯胺。用IR和1HNMR对该液晶化合物的结构进行了表征,用DSC和热台偏光显微镜(POM)对该化合物的液晶行为进行了分析,结果表明,4-烯丙氧基苯亚甲基(-4’-丁氧基)苯胺是一种单向性近晶型液晶。

The Schiffbase liquid crystal compound with terminal vinyl group, 4-allyloxy phenylmethylene （-4＇- butoxyl）aniline was synthesized by the substitution, reduction and addition reaction. The chemical structure of the liquid crystal compound was confirmed by IR and ^1 HNMR, The liquid crystalline properties of the liquid crystal compound was investigated by DSC and POM with hot stage. The results showed that 4-allyloxy phenylmethylene （-4＇-butoxyl） aniline exhibited one-way smectic liquid crystal behavior.
