Used as a fluorescent probe in biochemical and analytical applications due to its strong emission properties upon binding to specific metal ions or biomolecules. Its structure allows for high selectivity and sensitivity in detecting trace amounts of analytes in environmental and biological samples. Commonly applied in research settings for imaging intracellular processes and monitoring metal ion concentrations in real time. Also explored as a component in chemosensors for detecting heavy metals in aqueous systems. Shows potential in photodynamic therapy and optoelectronic devices because of its extended π-conjugation and photochemical stability.
