传统共轭高分子的三线态能级较低（一般小于2.7eV）和高三线态能级的非共轭聚乙烯咔唑PVK的双极传输性能较差为制约高分子磷光材料效率提升的瓶颈，但基于芳基氧磷单元的非共轭高分子表现出良好的双极传输特性和极宽的三线态能级调控窗口（2.2 - 3.0 eV），在构建高效高分子磷光材料方面具有创新机遇。本项目旨在采用这类芳基氧磷高分子作为主体骨架，采用侧链结构化学掺杂高效磷光掺杂剂，通过调控三线态能级和双极传输特性两个核心要素，针对不同发光颜色对三线态能级的匹配要求，发展一类具有非共轭结构和双极传输特性的蓝光、绿光和红光高分子磷光材料，力争性能指标全面达到有机小分子磷光材料的水平，为突破有机小分子磷光材料的国际专利保护，面向低成本的溶液加工工艺发展高效磷光高分子材料提供全新途径。

Unlike the typical conjugated polymers,the non-conjugated poly(aryl phosphine oxide)s (PAPOs) have excellent bipolar transport capabilities and very wide tuning window for the triplet energy in the range of 2.2 - 3.0 eV.Therefore,PAPOs show great potential for the design of electrophosphorescent polymers (PhPs).In this project,we aim to develop novel blue-,green- and red-emitting PhPs with non-conjugated main chain by adopting PAPOs as the host,which is covalently tethered with different color phosphorescent dopants.The performance of these resulant PhPs is expected to be close or comparable to that of small molecular phosphors.We believe that,this study will further pave the way for the development of highly efficient PhPs.
