荧光稀土铕液晶离聚物的合成与表征

Preparation and characterization of fluorescent rare-earth liquid crystal ionomers

本实验采用2,5-二羟基苯甲酸、对联苯酚、癸二酰氧基苯甲酰氯,无水氯化铕制备稀土铕主链液晶离聚物,采用红外、核磁、偏光显微镜与荧光光度计对其结构、液晶类型与荧光性能进行了表征。

In this paper, fluorescent liquid crystalline ionomers which emit red fluorescence were synthesized using 2, 5-dihydroxybenzoic acid, 4, 4-dihydroxy p-biphenyls, sebacyloxy benzoyl chloride and anhydrous EuCl3. The structure, liquid crystal type and fluorescence property were characterized by infrared spectrum, nuclear magnetic resonance, polarizing microscope and fluorescence photometer.
