Bis(2-(2,4-difluorophenyl)pyridinato-N,C²′)(picolinato)iridium(III) (FIrpic)(CAT: M440047) is a benchmark blue phosphorescent emitter widely applied in organic light-emitting diodes (OLEDs). With difluorophenylpyridine cyclometalating ligands and a picolinato ancillary ligand, FIrpic delivers highly efficient sky-blue emission with strong color purity and excellent photoluminescence quantum yield. Its iridium(III) center ensures effective spin–orbit coupling, enabling triplet exciton harvesting and near-unity internal quantum efficiency. Known for its balanced charge transport, robust thermal stability, and reliable thin-film morphology, FIrpic is a standard emitter in high-performance OLED displays and solid-state lighting. It remains one of the most important blue phosphorescent materials in next-generation optoelectronic technologies.
