针对传统共轭高分子因三线态能级过低（< 2.7 eV）而难以实现蓝光TADF的问题，本项目旨在采用聚芳醚作为高分子骨架，发展具有热活化延迟荧光（TADF）效应的蓝光聚芳醚材料。核心在于设计合成高性能的蓝光TADF小分子作为聚合单体，通过均聚或共聚的连接方式形成聚芳醚结构，期望利用O原子来打断共轭，避免相邻蓝光TADF单元之间的电子耦合，从而使得高分子能够保持小分子的蓝光TADF特性。同时，采用蓝光TADF聚芳醚作为主体和荧光染料作为客体，开发低成本、高效率和良好器件稳定性的蓝绿红三基色超荧光体系，为蓝光高分子TADF材料的设计与应用开辟出新途径。

As for the typical conjugated polymers, it seems to be very difficult to realize blue thermally activated delayed fluorescence (TADF) because of their lower triplet energies than 2.7 eV. To solve such a problem, herein we plan to develop blue poly(arylether)s showing excellent TADF. In this case, the blue TADF small molecules are linked together by oxygen to form a basic poly(arylether) structure, where the conjugation of the polymeric backbone is interrupted to avoid the electronic communication between two neighboring TADF units. Consequently, the resultant polymer is expected to keep the blue TADF emission of the small molecule. At the same time, the blue, green and red hyperfluorescence with low-cost, high-efficiency and good device stability will also be exploited by using the blue poly(arylether)s as the hosts and the fluorescent emitters as the guests. We believe that this project will shed light on the design and application of efficient blue TADF polymers.
