Acetylacetonatobis(2-phenylpyridine)iridium Structural

What is Acetylacetonatobis(2-phenylpyridine)iridium?

Description

Like?Ir(ppy)3, bis[2-(2-pyridinyl-N)phenyl-C](acetylacetonato)iridium(III), or?Ir(ppy)2(acac), is one of the most studied OLED materials due to its high quantum yields. When doped into 3,5-Diphenyl-4-(1-naphthyl)-1H-1,2,4-triazole (TAZ), very high external quantum efficiencies of (19.06 ± 1.0%) and luminous power efficiencies of 60±5 lm/W were achieved. This was attributed to the nearly 100% internal phosphorescence efficiency of Ir(ppy)2(acac), coupled with balanced hole and electron injection, and triplet exciton confinement within the light-emitting layer.

The Uses of Acetylacetonatobis(2-phenylpyridine)iridium

(ppy)₂Ir(acac) used in green phosphorescent OLED devices as dopant/emitter achieved high brightness of 130800 cd m_2 at a current density of 1550 mA cm_2 (13 V), and high quantum efficiency (15~16%).
