**Two new iridium complexes with pyrazine** derivatives as ligands (see Figure) were synthesized. The electroluminescent devices based on these metal complexes emit orange–red light at ∼ 610 nm with exceedingly high brightness and external quantum, current, and power efficiencies.
## Abstract A new series of highly efficient red‐emitting phosphorescent Ir(III) complexes, (Et‐CVz‐PhQ)~2~Ir(pic‐N‐O), (Et‐CVz‐PhQ)~2~Ir(pic), (Et‐CVz‐PhQ)~2~Ir(acac), (EO‐CVz‐PhQ)~2~Ir(pic‐N‐O), (EO‐CVz‐PhQ)~2~Ir(pic), and (EO‐CVz‐PhQ)~2~Ir(acac), based on carbazole (CVz)‐phenylquinoline (PhQ) ma
