tetradentate cyclometalated Pt(II) complex (PtN3N) is developed as an efficient, stable phosphorescent emitter. One PtN3N device exhibits an estimated LT97 of 2057 h at an initial luminance of 1000 cd m–2, while maintaining an external quantum efficiency of 15.3% at such high brightness, demonstrating performance to overcome the last technical barrier to the commercialization of Pt complexes for many applications

Highly efficient and stable palladium complexes that exhibit both phosphorescence and delayed fluorescence are developed. It is demonstrated that the emission from the two processes can be separately tuned through rational ligand modification. External quantum efficiencies over 20% are achieved and stable devices demonstrate an operational lifetime to 90% initial luminance estimated at over 20 000
