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 emission profile. Suitable for use in both small-molecule and solution-processed OLED architectures. Also investigated in sensing applications and as a photocatalyst in certain organic transformations due to its long-lived excited states and photostability.
