Used as a phosphorescent emitter in organic light-emitting diodes (OLEDs), particularly in red and near-infrared emission layers. Its strong spin-orbit coupling due to the iridium metal center enables efficient triplet harvesting, resulting in high electroluminescence efficiency. The trifluoromethyl and fluorinated pyridinyl ligands enhance thermal stability and electron transport properties, making it suitable for use in high-performance, long-lifetime OLED displays and lighting devices. Commonly doped into host materials within the emissive layer to prevent concentration quenching and improve color purity.
