摘　　要：以3-溴丙烯、4-羟基苯甲酸和4-羟基联苯为原料,经Williamson醚化、羧酸酰化和酯化反应合成了4-烯丙氧基苯甲酸联苯酯液晶单体,其结构经1HNMR和IR表征。DSC和偏光显微镜观察表明液晶单体呈向列相。A liquid-crystal monomer, 4- （ 4-AUyloxybenzoyloxy ） biphenyl, was synthesized from 3- bromopropene, 4-hydroxybenzoic acid and 4-hydroxy diphenyl by Williamson reaction, acylation and esterifieation. The structure was confirmed by ^1H NMR and IR. The monomer exhibited nematic phase liquid-crystal hehavior which was observed by DSC and polarized optical microscope.
