| 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. |
