具有荧光性手性液晶高分子的制备与表征

Preparation and characterization of fluorescent chiral liquid crystal polymers

本文采用手性液晶单体、稀土铕配合物与聚甲基含氢硅氧烷接枝共聚,制备了一种能够发射红色荧光的手性液晶高分子。采用红外光谱、核磁共振、偏光显微镜与荧光光度计,对其化学结构、液晶织构和荧光性能进行了表征。

In this paper, chiral liquid crystalline polymers which emit red fuorescence were synthesized by a graft copolymerization of chiral liquid crystal monomer, rare earth europium complex and polymethyl hydrosiloxane. Infrared spectrum, nuclear magnetic resonance, polarizing microscope and fuorescence photometer were used to characterized the chemical structure, liquid crystal texture and fuorescence property of fuorescent chiral liquid crystalline polymers.
