| 中文摘要: |
| 用于有机发光二极管（OLED）的红光和绿光磷光金属配合物材料在稳定性和发光效率方面均已达到了目前产业化应用的要求，而蓝光磷光配合物则在稳定性方面无法达到应用条件。高能量的激发态以及d-d态引起的配合物分解是造成蓝光磷光OLED器件稳定性差的原因之一。采用四齿配体开发d8金属配合物是同时提升配合物发光效率和稳定性的途径之一，有望在蓝光磷光材料和器件应用方面取得突破。本文总结了基于四齿配体的蓝光铂（Ⅱ）和钯（Ⅱ）配合物的研究进展，通过探讨配体结构对配合物光物理性质和稳定性的影响，为继续开发具有应用前景的蓝光金属配合物材料提供了指导性方向。 |
| 英文摘要: |
| Red and green phosphorescent metal complexes in OLEDs have shown performances that meet the practical industrial applications in terms of device efficiency and stability, whereas the applications of blue phosphorescent metal complexes have been hampered by their unsatisfactory stability. High energy of the excited states and thermal population of d-d states are conceived to cause the decomposition of blue light-emitting complexes. The development of d8 blue phosphorescent transition metal complexes by using tetradentate ligand is expected to enhance the emission efficiency and stability simultaneously. Progress in blue light-emitting platinum(Ⅱ) and palladium(Ⅱ) complexes and their performances in OLEDs is reviewed. By shedding light on the ligand structures-photophysical and stability relationships, we try to provide suggestions to the future effort for developing blue light-emitting metal complexes. |
