摘 要手性侧链液晶材料由于特殊螺旋结构的存在使其具有独特光电的性质，在生物医学能源、光学、显示等众多领域中具有巨大的潜在应用价值。手性液晶弹性的性质受手性液晶交联剂性质的影响，因此合成新型的手性液晶交联剂具有重要的研究意义。本研究以樟脑酸为手性中心，经过成醚成酯反应，制备一种新型的手性液晶交联剂 4-(4-烯丙氧基)苯甲酰氧基-4'-羟基苯樟脑酸双酯。采用红外光谱分析仪(FTIR)和核磁共振氢谱(1H-NMR)对手性液晶交联剂的化学结构进行了测试，结果表明所制备的液晶交联剂在结构上符合分子设计。采用偏光显微镜(POM)单体的液晶织构进行了观察，观察结果表明单体为胆甾相液晶。采用差示扫描量热仪(DSC)对液晶单体的液晶性能进行了研究，测试结果表明该单体具有较宽的液晶相区间，在制备新型手性液晶弹性体的研究中具有较好的应用价值。关键词：液晶；交联剂；手性；液晶弹性体 AbstractChiral liquid crystal elastomers have been extensively studied in the field of materials in consequence of their unique characteristics originated from the atomic chiral centers and helical conformations, which make them promising for applications in displays, solar-energy harvesting, optics and photonics, and biomedicine. The properties of chiral liquid crystal elastomers are greatly affected by the crosslinking agents of chiral liquid crystal. In this study, I II4-hydroxyphenyl-4'-allyloxybenzoate camphoric acid diester was synthesized by ether-ester reaction. Through the FTIR and 1H-NMR to study the chemical structure and liquid crystal properties of the crosslinking agent, the results indicate that the structure of the liquid crystal crosslinking agent accords with the molecular design. Through the Differential scanning calorimeter (DSC) and POM to analyze the texture and the characteristics of the crosslinking agent. Experimental result indicates that the crosslinking agent is a cholesteric phase with a wide liquid crystal phase range and it has a good application value in th...
