低熔点液晶冠醚的合成

SYNTHESIS OF LOW MELTING MESOMORPHIC CROWN ETHERS

文献上所报道的冠醚液晶的熔点都相当高。为研究液晶冠醚的光电性质、溢控离子传输性质以及它们在显示和仿生膜中的应用,我们设计并合成出了八种(3-10)低温冠醚液晶,通过元素分析,IR、1HNMR和MS确证了它们的结构,由DSC和织构图(Texture)测定了它们的液晶性质.

The melting points of crown ether liquid crystals reported so far were quite high. In order to study their opto-electric and theromcontrolling ions transportation properties,and their applications in display and biomimetic membranes,the synthesis of room-temperature and low-temperature crown ether liquid crystals (1-8) were carried out. Their structures were eluciated by elementary analysis, IR,1 HNMR and MS. DSC and Textures were used in determinating of their mesomorphic properties.
