Highly Efficient Blue‐Emitting Cyclometalated Platinum(II) Complexes by Judicious Molecular Design

Deep-blue emitters based on cyclometalated platinum(II) complexes were synthesized, characterized, and used in organic light-emitting devices. The complexes with tetradentate ligands exhibited improved photophysical properties over iridium analogues, and one such compound achieved a peak external quantum efficiency (EQE) of 23.7 %.
