Used as a phosphorescent emitter in organic light-emitting diodes (OLEDs), particularly in display and lighting technologies. Its strong spin-orbit coupling enables efficient conversion of electrical energy into light, resulting in high device efficiency. Commonly employed in red or near-infrared emitting layers due to its tunable emission properties. Suitable for use in both small-molecule and solution-processed OLEDs, making it valuable for advanced optoelectronic applications. Exhibits good thermal and electrochemical stability, contributing to longer operational lifetimes in devices.
