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, making it suitable for red or near-infrared emission layers. The complex enhances device efficiency due to its long excited-state lifetime and good color purity. It is incorporated into the emissive layer of OLEDs, often doped into a host matrix to prevent self-quenching. Also explored in photocatalytic systems and as a sensitizer in advanced oxidation processes due to its photostability and tunable redox properties.
