Ir(mppy)3, green light emitting phosphorescent dopant
Used in highly efficient OLED and TADF-OLED devices
Ir(mppy)3, Tris[2-(p-tolyl)pyridine]iridium(III), is widely used as a phosphorescent dopant which emits green light in highly efficient OLED and TADF-OLED devices. With three methyl groups attached to the ppy ligands, Ir(mppy)3 is more soluble than the widely known green emitter Ir(ppy)3.
When it is co-doped with Ir(ppz)3, Ir(mppy)3 devices show a slower efficiency roll-off and higher electroluminescent efficiencies due to improved recombination probability and suppressed exciton quenching.
