Used as a highly effective fluorescent sensor for detecting metal ions, particularly zinc (Zn²⁺) in biological and environmental samples. Its structure allows selective binding to zinc, resulting in a strong fluorescence turn-on response, making it valuable in cellular imaging and monitoring intracellular zinc levels. Also applied in supramolecular chemistry for constructing metallo-supramolecular assemblies due to its bidentate coordination sites. Shows potential in optoelectronic devices because of its favorable photophysical properties and stability under UV irradiation.
