Used as a fluorescent sensor for detecting metal ions, particularly zinc and copper in solution. Its structure allows selective binding to these ions, resulting in a measurable change in fluorescence intensity. Employed in environmental monitoring to detect trace metal contamination in water samples. Also applied in biochemical research for imaging metal ion distribution in cells due to its ability to cross cell membranes and emit visible light upon binding. Shows potential in developing optoelectronic devices because of its strong luminescent properties and thermal stability.
