Used as a phosphorescent emitter in organic light-emitting diodes (OLEDs), particularly in display and lighting technologies. Its strong spin-orbit coupling enables efficient triplet harvesting, resulting in high electroluminescence 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, offering stability and color purity. Also explored in photocatalytic systems and as a sensitizer in energy transfer processes.
