Light-Emitting Devices: High-Efficiency Polymer Light-Emitting Devices with Robust Phosphorescent Platinum(II) Emitters Containing Tetradentate Dianionic O∧N∧C∧N Ligands (Adv. Mater. 46/2013)

[Pt(O∧N∧C∧N)]‐type complexes are used as single emitters in solution‐processed polymer light‐emitting diodes (PLEDs), with a maximum external quantum efficiency (EQE) of 15.55% for green and 12.73% for white devices, respectively. These values, determined by Chi‐Ming Che and co‐workers, as described...

Description
Summary:[Pt(O∧N∧C∧N)]‐type complexes are used as single emitters in solution‐processed polymer light‐emitting diodes (PLEDs), with a maximum external quantum efficiency (EQE) of 15.55% for green and 12.73% for white devices, respectively. These values, determined by Chi‐Ming Che and co‐workers, as described on page 6765, are the highest values ever achieved for PLEDs based on Pt(II) complexes and white PLEDs based on single emitters.
