摘要： 合成了端烯基液晶冠醚新化合物,通过紫外光谱、红外和拉曼光谱以及质谱对液晶冠醚的结构进行了详细的分析;并利用差示量热扫描(DSC)方法和热台偏光显微镜研究了液晶冠醚的热性质及织构,探讨了液晶冠醚的结构与相态的关系。

Abstract: Four terminal-vinyl liquid crystal crown ethers(LCCEs)(ⅠⅡ,Ⅲ,Ⅳ)containing 15-crown-5 were synthesized. Their structures were confirmed by IR, NMR, MS, and EA. The relationships between these LCCEstructures and their UV, MS,IR and LR(Laser Raman)spectra were discussed in detail. Their thermodynamic properties and textures were studied by using the differential scanning calorimetry(DSC)and hotstage light-polarized microscope.The results showed that only the biphenyl compounds(Ⅰ,Ⅱ) possessed the liquid crystalline properties.

Key words: Liquid crystal crown ether, Synthesis, Phase change, Texture
