Used as a high-performance near-infrared (NIR) fluorescent dye in bioimaging and optical sensing applications. Its strong absorption and emission in the NIR region allow deep tissue penetration with minimal autofluorescence, making it ideal for in vivo imaging. The long alkyl chains enhance solubility in organic solvents and improve compatibility with lipid membranes, enabling cell membrane labeling and tracking. It is also employed in photodynamic therapy research due to its ability to generate reactive oxygen species under light irradiation. Additionally, this compound serves as a fluorophore in the development of chemosensors for detecting metal ions or biomolecules in complex biological environments.
