摘  要：荧光高分子是实现可控发光、柔性显示和多功能化等技术的关键材料之一，在特种工程塑料聚芳醚腈分子侧链上，通过酰胺化反应引入聚集诱导发光基团，合成了一种本征型的荧光高分子材料.该聚合物表现出典型的聚集诱导荧光增强特性，聚集态荧光呈明亮的蓝绿光发射.借助羧基反应性，聚合物分子链可在钙离子存在时发生更紧密的聚集，从而提升发光强度.同时，四苯乙烯刚性结构的引入进一步提高了材料耐热性能，聚合物的5%热分解温度为417℃.所制备的耐高温荧光聚芳醚腈可作一种多功能化的高分子材料，可应用于光学显示与可视化传感等高新光学领域.

Abstract：Fluorescent polymer is one of the key materials for flexible display,controlled luminescence and multifunctional science.An intrinsic fluorescent polymer was synthesized by introducing an aggregation-induced emission monomer into the side chain of polyarylene ether nitrile (PEN),which was a type of special engineering plastic,containin-induced emission enhancement polymer.By virtue of carboxyl reactivity,the polymer could be further aggregated in the presence of calcium ions to enhance the fluorescence intensity.In addition,5% thermal decomposition temperature of the polymer increased from 407℃ to 417℃ after the introduction of tetra styrene structure,which benefited the thermal resistance of the polymer due to the rigid structure.The synthesi
