P‐160: White Organic Light‐Emitting Diodes Based on Single White Dopant of Heteroleptic Tris‐Cyclometalated Iridium(III) Complex

Abstract We report white organic electroluminescent device based on single white dopant, Ir(dfppy) 2 (pq). The similar phosphorescent lifetime of two ligands lead to emit luminescence in two ligands at the same time, the emission wavelength of single white dopant has a broad peak and emit white color without the intramolecular energy transfer.
