Abstract

N) bzq ligand. A LEC with [Ir(bzq)(2)(biq)][PF6] as the emitter was fabricated which showed a deep red emission (662 nm) with a luminance of 33.65 cd m(-2), yielding a current efficiency of 0.33 cd A(-1) and a power efficiency of 0.2 lm W-1. Most importantly, the LEC based on [Ir(bzq)(2)(biq)][PF6] demonstrated a lifetime of 280 hours which is among the longest device lifetimes reported for any deep red light emitting LEC.
