Used as a fluorescent probe in bioimaging applications, particularly for cellular labeling and tracking due to its strong emission in the visible range. Exhibits good photostability and membrane permeability, making it suitable for live-cell imaging without requiring fixation. Also employed in the development of sensors for metal ions, where it acts as a signaling unit in chemosensors by changing fluorescence upon binding to specific cations. Its conjugated structure allows integration into larger molecular systems for targeted delivery in diagnostic applications.
