Abstract

[Pt(O(∧) N(∧) C(∧) N)]-type complexes are used as single emitters in solution-processed PLEDs with maximum EQEs of 15.55% for green and 12.73% for white devices, which are the highest values ever achieved for PLEDs based on Pt(ii) complexes.

Keywords: monochromic emission; platinum(ii) complexes; polymer light-emitting devices; tetradentate O∧N∧C∧N ligand; white emission.
