Used in research as a fluorescent probe for detecting metal ions in environmental and biological samples. Its high sensitivity to pH changes makes it suitable for monitoring intracellular acidity in live-cell imaging. Also applied in the development of chemosensors for heavy metal detection in water systems. Shows potential in photodynamic therapy due to its light-induced reactive oxygen species generation. Employed in organic light-emitting diodes (OLEDs) as an emissive layer component for green fluorescence.
