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 fluorinated ligands enhance electron transport, improve thermal stability, and help tune the emission color through electronic effects. Commonly employed in display technologies and solid-state lighting where stable, efficient red emission is required. Also investigated in optoelectronic devices and sensors due to its long-lived excited states and robust performance under operational conditions.
