Used as a fluorescent probe in biological imaging due to its strong emission properties and sensitivity to environmental polarity. It is effective in detecting intracellular pH changes and monitoring membrane dynamics in live cells. Also applied in photodynamic therapy research as a photosensitizer that generates reactive oxygen species under light irradiation. Its structural flexibility allows for use in designing sensors for metal ions and biomolecules. Additionally, it serves as a building block in synthesizing more complex bioactive molecules and optoelectronic materials.
