鉴于大尺寸、柔性和低成本加工为未来有机照明光源的发展方向之一和材料是制约高光效和长寿命的瓶颈问题，不同于蒸镀工艺的有机小分子白光OLED，本项目将面向低成本的溶液加工路线（喷墨打印和印刷工艺），发展三类具有“溶液加工特性”的白光高分子材料（全磷光单一高分子白光材料、具有电子限制机制的单一高分子白光材料、全磷光树枝状分子白光材料）。通过突破蓝光、橙光磷光材料和高三线态能级主体材料的分子设计，开发出具有国际特色的白光高分子材料体系，力争在基础研究方面持续保持在白光高分子材料方面的国际领先地位，在应用基础研究方面采用溶液加工工艺开发出60-80 lm/W的白光高分子器件，形成对本领域发展具有带动和引领作用的创新性研究成果。

This project aims to develop the solution-processed dendrimers and polymers for white OLED/PLEDs, based on the single polymer system for making white light proposed by our group in 2004, different from polymer blend system, which is one of two typical methods for making white light, and on the self-host phosphorescent dendrimers with different generation and density of carbazole moiety as dendron, different from the traditional phosphorescent dendrimers using none-active dendron. The major findings with the innovation and breakthrough are focused on the single polymer system for white light with triplet state, the single polymer system for white light with electron-trapping effect and solution-processed phosphorescent dendrimers for white OLED/PLEDs with the power efficiencty of 60-80 lm/W. Several new concepts, new methods are expected to design and prepare the above mentioned polymer systems and the basic research achievements in the field of white electroluminescent materials are expected to be on world-leading class with good impact.
