摘　　要：通过分子结构设计,对聚苯醚进行化学改性,合成了以聚苯醚为主体,侧链接枝三嗪基团的新型改性聚苯醚。最终的产物PPO-CzTA是由溴代聚苯醚与含有羟基的三嗪基团发生C-O偶联反应得到的,并对其进行了性能表征。结果显示,通过核磁和红外光谱的分析,确定了PPO-CzTA的结构,并且,接入三嗪单元的聚苯醚显示出了优异的热稳定性,并展现出了良好发光性能。The polyphenylene ether was chemically modified by molecular structure design, and a novel modified polyphenylene ether with polyphenylene ether as the main component and side-chained triazine group was synthesized. The final product, PPO-CzTA, was obtained by C-O coupling reaction of a brominated polyphenylene ether with a hydroxyl group-containing triazine group, and its performance was characterized. The results showed that the structure of PPO-CzTA was confirmed by the analysis of nuclear magnetic and infrared spectra, and the polyphenylene ether connected to the triazine unit showed excellent thermal stability and exhibited good luminescence properties.
