4,4’二(4-烯丙氧基苯甲酸)苯酯双功能基团液晶体的制备与性能
Synthesis and property of liquid crystal 4,4’-bis (4-allyloxy-benzoyloxy)pheny
【摘要】 以3-溴丙烯、4-羟基苯甲酸和对苯二酚为主要原料,经Williamson醚化、羧酸酰化和酯化反应制备了4,4’-二(4-烯丙氧基苯甲酸)苯酯双功能基团液晶单体,通过FT-IR,1H-NMR,13C-NMR对其结构进行了表征。用DSC,XRD,偏光显微镜((POM)研究了单体的液晶性能,结果表明该单体熔点为164℃,清亮点为244℃,为向列相液晶。
【Abstract】 The new Liquid crystal monomer 4,4’-bis(4-allyloxy-benzoyloxy)phenyl with double functional group was synthesized from 3-bromopropene,4-Hydroxybenzoic acid and hydroquinone by Williamson reaction,acylation and esterification.Its structure was confirmed by FT-IR,1H-NMR and 13C-NMR.The molecule exhibited nematic phase liquid crystal behavior which was observed by DSC,XRD and POM.The temperature range of liquid crystalline is at 164-244℃.
