Bis(2-methylphenylquinolinato)iridium(acetylacetonate) (Ir(mphq)₂(acac))(CAT: M440040) is a phosphorescent iridium(III) complex engineered for high-performance red emission in organic light-emitting diodes (OLEDs). Incorporating two methyl-substituted phenylquinoline ligands and an ancillary acetylacetonate, Ir(mphq)₂(acac) delivers efficient, saturated red photoluminescence with strong color purity and excellent thermal stability. Its ability to harvest both singlet and triplet excitons enables near-unity internal quantum efficiency, while its robust molecular framework ensures stable thin-film morphology and extended operational lifetime. Widely applied in OLED displays and solid-state lighting technologies, Ir(mphq)₂(acac) provides high brightness, reliability, and efficiency, making it an important red emitter for next-generation optoelectronic applications.
