Used as a fluorescent probe in biological imaging due to its strong absorption and emission properties in the visible range. It selectively binds to cellular membranes and stained organelles, allowing visualization of membrane dynamics in live cells. Also applied in photodynamic therapy research as a photosensitizer that generates reactive oxygen species under light exposure. Its stability in aqueous media and low cytotoxicity make it suitable for in vitro diagnostic applications. Additionally, it serves as a spectral sensitizer in dye-sensitized solar cells, improving light harvesting efficiency.
