摘要: 本文以二茂基二氯化铂为催化剂,使含液晶基元的单体4-(烯丙基氧)-4'-(4'-羧基苯并15-冠-5)-α,ω-二苯氧丁烷和聚甲基硅氧烷进行硅氢加成反应,合成了一种新的冠醚侧链液晶聚硅氧烷配体及其钠配合物。采用DSC和偏光显微镜方法研究了单体、配体和配合物的液晶行为,发现它们均具有热致液晶性。

关键词: 侧链液晶聚硅氧烷, 冠醚, 钠配合物

Abstract: Anew ligand and sodium complex of poiysiioxanes with liquid-crystal crown-ether-containing side chain woe synthesized by the hydrosilyiation reaction using mesogenic monomer, 4-(allyloxy)-4' -(4' -carboxybenzo-15-crown-5)-α,to-diphenoxybutane and poly(methylsiloxane) with Cp2PtCl2 as catalyst.The liquid crystalline behavior of the monomer, liganci and complex was studied by DSCand polarized optical microscopy.It was found that they are thermotropic.

Key words: Side chain liquid crystal polvsiloxanes, Crown ether.Sodium complex
