Used as a fluorescent sensor for detecting metal ions, particularly zinc (Zn²⁺) in biological and environmental samples. Exhibits high selectivity and sensitivity due to its ability to bind with metal ions and produce a measurable fluorescence response. Applied in cellular imaging to monitor intracellular zinc levels, aiding in the study of neurological processes and diseases related to metal ion imbalance. Also utilized in chemosensor development for environmental monitoring, where it helps detect trace metal contaminants in water and soil. Its structure allows for reversible binding, making it suitable for real-time and continuous monitoring applications.
