Used as a phosphorescent emitter in organic light-emitting diodes (OLEDs), particularly in blue-emitting layers. Its strong spin-orbit coupling due to the iridium metal center enables efficient triplet harvesting, resulting in high electroluminescence efficiency. The trifluoromethyl and fluorophenyl groups enhance electron transport properties and improve thermal stability, making it suitable for use in high-performance, long-lasting OLED displays and lighting devices. Commonly doped into a host matrix material to prevent concentration quenching and maintain color purity.
