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 qu...

Description
Summary: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 %.
