中文摘要： 基于铱金属配合物的绿/红色磷光材料及OLED已经被应用于商业化的显示屏中，蓝色磷光材料的稀缺制约了OLED技术的进一步发展。昂贵的铱金属且在地壳中含量稀少使材料成本居高不下，难以实现可持续性发展。发展廉价、高效率的磷光材料替代铱磷光材料成为必然趋势。本项目拟通过化学分子设计、合成一系列新型具有四齿配体螯合的铜(I)金属配合物，发展它们的合成与提纯方法，并进行结构表征。通过测试铜(I)配合物光物理、化学、热和光电性能，全面研究其光物理特性与化学结构之间的关系，探索铜(I) 配合物配体结构对其单/三线态间隙间穿越的调控机制。以此开发出具有高效磷光发射的单核中性铜(I)配合物，合理选择与之相匹配的有机功能材料, 通过增加空穴传输能力、平衡载流子、调控激子的复合区域或改变其浓度等来优化器件结构，制备出高效率蓝光器件，并对器件的稳定性进行研究。为实现高效低成本的OLED器件开发和应用做好基础性探索

英文摘要： Iridium complexes based green/red phosphorescent materials have been used in commercial display based on OLED, while few and low performance of blue phosphorescent materials has restricted the growth of OLED technology. Meanwhile, expensive iridium metal with rare abundance in the earth maintains the cost of materials, which hinder the sustainable development of OLED. Development of cheap phosphorescent materials with high efficiency to replace iridium complexes becomes an urgent demand. This proposal will focused synthetic method and characterization of a series of neutral tetradendated copper(I) [Cu(I)] complexes following molecular design and their purification. After measuring the photophysical, chemical, thermal and opto-properties of synthesized Cu(I) complexes, the relationship between these performance and molecular structure will be comprehensively studied. Then, how to modify he capability of intersystem crossing between the lowest singlet stat and the lowest triplet state of neutral Cu(I) complexes by structure of the ligands will be explored. On the basis of efficient Cu(I) complexes, highly efficient blue OLED will be demonstrated through improvement of hole transfer, balance of charge carries, and controlling the combination zone followed combining suitable materials for each layers. Finally, opera
