| 摘 要： | 设计合成对-7-辛烯羰氧基苯甲酸(A)和对-7-辛烯羰氧基苯甲酸胆固醇酯(B)，采取红外(FT-IR)、 核磁(1H-NMR)、质谱(MS)及元素分析法对其结构进行表征。用DSC分析B的相变温度，发现在78.3 ℃出现第一个相变峰，在123.4 ℃到达了各向同性的液相，介晶温度范围也较宽。用POM观察B液晶相态，选取90 ℃时进行拍摄出现明显的片状有序排列，说明化合物B具备液晶性能。

| Abstract: | The cholesterol benzylalmenoic acid derivative was designed and synthesized. The structure of the product was characterized by FIR, elemental analysis, 1H NMR and 13C NMR. The phase transition temperature of compound B was analyzed with DSC. It was found that the first phase transition peak appeared at 78.3 ℃, the isotropic phase was reached at 123.4 ℃, and the mesogenic temperature range was quite wide. Observation of the phase state of B’s liquid crystals with POM showed obvious orderly arrangement at 90 ℃, indicating that compound B possesses liquid crystal properties. |
