摘要
以丙烯酸、溴乙醇、对羟基苯甲酸、4-羟基苯甲醛、4-甲氧基苯胺为原料,经醚化、酰氯化、酯化和希夫碱反应合成中间体和液晶化合物。通过红外光谱、核磁共振等对化合物的结构进行表征。最后利用偏光显微镜测试目标产物的液晶性能。结果表明:含柔性间隔基的化合物具有很好的向列相液晶性能,目标化合物的液晶相宽度达到110℃左右,具有广阔的应用前景。
The related intermediates and liquid crystal was synthesized which was generated from acrylic acid, ethylene bromine, p-hydroxy benzoic acid, 4-hydroxy benzaldehyde and p-methoxyaniline by chloration, etherification, esterification and Schiff base reaction. The structures charactered by IR, NMR. The liquid crystalline properties of the production were investigated using polarized optical microscopy. The results showed that, the compounds with spacer had a good perforrnance of nematic liquid crystalline＇, liquid crystal temperature range was almost 110℃, there was a broad prospects for application.
