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.

蓝色和白色磷光发光体在OLED（有机发光二极管）工业中有很大的需求。它们是基于OLED技术的高能效全色信息显示设备（例如计算机和电视监视器、蜂窝电话等）和下一代照明设备（例如照明墙板、瓷砖或条纹）的关键成分。 与荧光发射体相比，磷光发射体可以使OLED的外部量子效率增加三倍或四倍，使得它们对于在节能OLED中的使用非常有吸引力。目前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类新的高效蓝色磷光铂化合物，可用于蓝色或白色OLED。初步的评价结果表明，这类新的蓝色发光体是非常有前途的应用在OLED。该提案寻求资金用于：（a）改进新蓝光发射体的大规模合成程序，以便向OLED公司提供样品进行评估;（B）研究OLED中新材料的性能、寿命和稳定性;（c）OLED行业验证新磷光材料。这项工作是朝着新排放器未来商业化/技术转让迈出的关键一步。
