Bis(2-(benzothiophen-3-yl)pyridinato-N,C³′)(acetylacetonato)iridium(III) (Ir(btp)₂(acac))(CAT: M440037) is a high-performance red phosphorescent emitter widely used in organic light-emitting diodes (OLEDs). Incorporating benzothiophene–pyridine ligands with an ancillary acetylacetonate, this iridium(III) complex delivers saturated deep-red emission with excellent color purity, high photoluminescence efficiency, and strong thermal stability. Its ability to harvest both singlet and triplet excitons ensures superior internal quantum efficiency, while its robust molecular structure supports stable film morphology and long device lifetimes. Ir(btp)₂(acac) is extensively applied in display and solid-state lighting technologies, where reliable red emission is essential for high-resolution, energy-efficient, next-generation optoelectronic applications.
