title: Efficient Cyclometalated Platinum(II) Complex with Superior Operational Stability.
abstract: A tetradentate cyclometalated Pt(II) complex (PtN3N) is developed as an efficient, stable phosphorescent emitter. One PtN3N device exhibits an estimated LT97of 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.
