摘要

聚合物电致发光材料成型加工简便、可大面积生产，可应用于大面积平板显示及固体照明器件。与红、绿光聚合物发光材料相比，蓝光聚合物电致发光材料在发光性能、材料寿命等方面仍然存在较大差距，这成为全色显示的瓶颈。通过在聚合物主链上引入大体积的取代基或侧链、形成具有三维空间共轭效应的支化结构或能量可转移的主客体结构等，来改善溶解性和光物理性能等，从而得到发光效率高、色纯度好、热力学性能优异且材料加工性能良好的蓝光聚合物电致发光材料。本文从材料设计的角度简要介绍了国内外蓝光聚合物发光材料的主要研究进展。

Abstract

Due to the good processability and ability in large area production

the light-emitting polymers have shown great potential in the application of flat displays and solid-state lighting in recent years. Compared with red and green light- emitting polymers

the blue polymers have poorer electroluminescence property and stability

which becomes the bottleneck of the full color displays. Through introducing bulky side chains or substitute groups

and forming three-dimensional branched structure or host-guest structure with energy transfer

the solubility and photophysical properties are improved in order to get blue fluorescent polymers with high luminescence efficiency

good color purity

thermostability and good processability. In this article

the main progress of the blue light-emitting polymers was briefly reviewed from the point of the materials design.
