Pt complex phosphorescent dopant with suppressed MMLCT properties was developed. Our Pt dopants demonstrates an EQE of 23.1%, a long lifetime of 132 hours (LT90 at 1000 nit). The energy difference between MLCT and metal centered triplet states seems to play an important role in the device lifetime improvement.
