N2 - This review explores the latest advancements of iridium(III) phosphorescent blue emitters by focusing on the design strategies employed for saturated blue phosphorescent OLEDs with enhanced operational lifetime. Saturated blue emission remains a challenging aspect of OLED technology, and iridium(III) complexes have emerged as promising materials to address this issue. The molecular design principles, ligand engineering and host materials that facilitate the achievement of highly efficient blue phosphorescent emission are explored. Additionally, various host-guest systems and device architectures that have been employed to prolong the operational lifetime of these OLEDs are systematically examined. The review highlights recent breakthroughs and prospects, including the synthesis of novel iridium(III) complexes, advanced device engineering strategies, and potential application in next-generation displays and lighting technologies. Therefore, this comprehensive analysis serves as a valuable resource for researchers and industry professionals engaged in the development of advanced OLEDs with improved efficiency and longevity. © 2024 Elsevier Ltd
