| 摘 要： | 从设计合成单体噻吩取代对苯二甲酸双(对甲氧基苯)酯入手,以FeCl3为催化剂,CHCl3为溶剂,合成了一种新型以聚噻吩为共轭主链的共轭聚合物.利用核磁共振(1H-NMR),红外光谱(IR)等方法表征了单体和聚合物的结构.利用差示扫描量热仪(DSC)、带热台的偏光显微镜(POM)、紫外光谱(UV)和荧光光谱(PL)研究了聚合物液晶性和光学性能.结果表明,该聚合物为无规聚合物.通过偏光显微镜观察,单体具有向列型液晶态纹影织构,而由于大体积刚性侧基破坏了聚合物的液晶性,聚合物分解温度之前未观察到该聚合物有明显的双折射现象.

| Abstract: | A novel polythiophene with directly attached bis(4-methoxyphenyl) terephthalate mesogen as pendant was synthesized by polymerization using FeCl3 as the catalyst and CHCl3 as the solvent.The proton nuclear magnetic resonance(1H-NMR) was used to analyze chemical structure of the polymer.The thermal properties and the optical properties of polymer were studied by means of DSC.POM.UV and PL.The results indicate that the polymer has the expected random structure.The monomer exhibits a typical texture of nematic liquid crystal,while the polymer does not show any optical anisotropy due to the bulky and rigid side chain. |
