Used as a fluorescent probe in bioimaging due to its strong emission properties, especially in cellular environments where detection of specific organelles or pH changes is required. Its structure allows for easy functionalization, making it a versatile building block in the synthesis of fluorophores and sensors. Commonly applied in the development of chemosensors for detecting metal ions and reactive oxygen species. Also explored in materials science for organic electronics due to its electron-deficient aromatic system and stability.
