Abstract

image

[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.
