Unlocking the full potential of TADF emitters using ubiquitous metals is challenging. Recently, we developed highly luminescent aluminum complexes with β-diketone ligands exhibiting TADF. These complexes have enabled high-efficiency solution-processed OLEDs with EQEs over 20%, and serve as superior sensitizers, producing narrow emission band OLEDs with a FWHM of 45 nm and EQEs exceeding 20%.
