摘　　要： 利用丙烯酰氯代替丙烯酸钾与4,4′-二(6-溴己氧基)联苯反应改进了制备4,4′-二[6-(丙烯酰氧基)己氧基]联苯(BAB6)的合成路线。改进前的反应温度较高,中间产物溶解度小,产物呈淡黄色,收率仅12.4%;改进后在室温反应,中间产物溶解度较高,产物呈白色,收率达到46.8%。采用1HNMR、13CNMR和元素分析对中间体和BAB6结构进行了表征。由改进后合成的单体,制备了具有快速响应的聚合物分散液晶(PDLC)膜,响应时间约2ms。扫描电子显微镜观察的结果表明,PDLC中形成了聚合物网络结构。 A mesogenic diacrylate monomer 4,4＇-bis[6-（ acryloyloxy） hexyloxy]biphenyl （ BAB6） was synthesized by two routes. The improved method was from the modified traditional method by substituting 4,4＇-bis[6-（ bromo） hexyloxy〗biphenyl with 4,4＇-bis[6-（ hydroxyl） hexyloxy]biphenyl to react with acryloyl chloride instead of potassium acrylate. Compared with the traditional method,the reaction temperature was lowered,the solubility of intermediate products was improved and the yield was increased from 12. 4% to 46. 8%. BAB6 was characterized by 1H NMR,13C NMR and elemental analysis. A fast response polymer dispersed liquid crystal（ PDLC） film was casted using BAB6 as the monomer,and the response time was about 2 ms. In addition,the morphology of the polymer network was investigated by SEM.
