中文摘要	以对羟基苯甲醛和氰基乙酸乙酯缩合生成α-氰基对羟基肉桂酸乙酯,再与4种酰氯反应生成α-氰基肉桂酸酯类液晶;以对羟基苯甲醛和氰基乙酸丙基苯酚酯缩合生成α-氰基对羟基肉桂酸丙基苯酚酯,再与2种烷基环己基甲酰氯反应生成α-氰基肉桂酸酯类液晶。目标化合物经MS分析确认了结构。通过差示扫描量热仪测量相变温度,对合成产物的液晶相态进行了研究;通过紫外分光光度计测量紫外光谱,研究了合成产物紫外吸收性能。在混合液晶中的应用实验表明,此类化合物可以作为具有液晶性能的紫外吸收剂添加到混合液晶中,改善液晶材料的抗紫外性能。; Ethyl α-cyano-4-hydroxycinnamate was synthesized by 4-hydroxybenzaldehyde and ethyl cyanoa-cetate. Four ester liquid crystal compounds were synthesized by four chloride and ethyl α-cyano-4-hydroxycinnamate. 4-propylphenol α-cyano-4-hydroxycinnamate was synthesized by 4-hydroxybenzaldehyde and 4-propylphenol cyanoacetate. Two ester liquid crystal compounds were synthesized by two alkyl-cyclohexyl carbonyl chloride and 4-propylphenolα-cyano-4-hydroxycinnamate. All the compounds were characterized by MS, and their phase transition temperatures were measured by DSC. Ultraviolet absorption spectra of them were measured by UV spectrophotometer. Their properties of anti-UV in the liquid crystal mixtures were studied. The result shows that such compounds can be added to liquid crystal mixtures as UV absorbent, thus improving liquid crystal mixtures' anti-UV properties.; 国家“863”计划资助项目(No.2008AA03A304)
