Used as a phosphorescent emitter in organic light-emitting diodes (OLEDs), particularly in display and lighting technologies. Exhibits high efficiency and stability due to strong spin-orbit coupling from the iridium metal center, enabling effective harvesting of both singlet and triplet excitons. Commonly employed in red or near-infrared emitting layers owing to its tunable emission through ligand modifications. Suitable for use in dopant materials within emissive layers of OLED devices, contributing to high color purity and long operational lifetimes. Also explored in sensing and photoredox catalysis applications due to its photophysical properties.
