Used as a fluorescent probe in biological imaging due to its strong photostability and high quantum yield. It selectively binds to cellular membranes and allows visualization of membrane dynamics in live cells. Also employed in optoelectronic devices as an emissive layer component in organic light-emitting diodes (OLEDs) thanks to its efficient red emission. Additionally, serves as a photosensitizer in photoredox catalysis for organic transformations under visible light irradiation.
