Used as a fluorescent probe in biological imaging due to its strong absorption and emission properties in the near-infrared region. Enables visualization of cellular structures and tracking of biomolecules in live cells with minimal background interference. Also applied in photodynamic therapy research for targeted cell activation. Its lipophilic nature allows easy penetration through cell membranes, making it suitable for staining intracellular components. Additionally, employed in the development of sensors for detecting environmental changes such as pH and polarity in microenvironments.
