Used as a fluorescent probe in biological imaging due to its strong emission in the visible range and good photostability. It selectively accumulates in cellular membranes, making it useful for visualizing membrane structures in live cells. Also employed in optoelectronic applications, such as organic light-emitting diodes (OLEDs), where it acts as an emissive layer component. Its ionic nature enhances solubility in polar solvents, facilitating solution-based device fabrication. Additionally, it serves as a photosensitizer in photoredox catalysis for organic transformations under visible light.
