Validation of new blue and white pt (II) phosphorescent emitters for OLEDs

有机发光二极管（oled）行业对蓝光和白光发光器件的需求量很大。它们是基于OLED技术的高能效全彩信息显示设备（如计算机和电视显示器，手机等）和下一代照明设备（如照明墙板，瓷砖或条纹）的关键成分。与荧光发射器相比，磷光发射器可以使有机发光二极管的外部量子效率提高三倍或四倍，使其在节能有机发光二极管中非常有吸引力。目前还没有稳定的蓝色磷光化合物可用于oled。我们的团队最近发现了一种新型高效的蓝色磷光铂化合物，可用于蓝色或白色oled。初步评价结果表明，这种新型蓝色发射体在oled中应用前景广阔。该提案寻求资金用于(a)改进大规模合成新蓝色发射器的合成程序，以便将样品提供给oled公司进行评估，(b)调查oled中新材料的性能，寿命和稳定性，以及(c) oled行业对新磷光材料的验证。这项工作是迈向新排放者未来商业化/技术转让的关键一步。

Blue and white phosphorescent emitters are in great demand in OLEDs (organic light emitting diodes) industry. They are the key ingredients for highly energy efficient full-color information display devices (e.g. computer and TV monitors, cellular phones etc) and next generation lighting devices (e.g. lighting wall panels, tiles, or stripes) based on OLED technologies. Compared to fluorescent emitters, phosphorescent emitters can triple or quadruple the external quantum efficiency of OLEDs, making them highly attractive for use in energy-efficient OLEDs. Currently no stable blue phosphorescent compounds are available for OLEDs. Our group has recently discovered a new class of highly efficient blue phosphorescent platinum compounds that can be used in either blue or white OLEDs. Preliminary evaluation results indicate that this new class of blue emitters is very promising for applications in OLEDs. This proposal seeks funding for (a) improved synthetic procedures for large-scale synthesis of the new blue emitters so that samples can be provided to OLEDs companies for evaluation, (b) the investigation of performance, lifetime and stability of the new materials in OLEDs, and (c) the validation of the new phosphorescent materials by OLEDs industry. This work is a key step toward future commercialization/technology transfer of the new emitters.
