Abstract
Phosphorescent Organic Light-Emitting Diodes
In article number 2409394, Sunwoo Kang, Wan Pyo Hong, Hyoung Yun Oh, Taekyung Kim, and co-workers present groundbreaking research on blue PHOLEDs featuring a novel tetradentate Pt(II) emitter with a spirofluorene-carbazole unit. This design suppresses vibration modes, achieving 50.3% EQEmax and 589 hours of LT70, marking a major advancement in ultra-pure blue emission, efficiency, and durability for industrial use.
