Used as a fluorescent probe in biochemical and analytical applications due to its strong emission properties upon excitation. It serves in the detection of metal ions, particularly aluminum and zinc, in solution by exhibiting measurable changes in fluorescence intensity. Employed in the development of chemosensors for environmental monitoring and cellular imaging. Also acts as a building block in organic synthesis for conjugated systems used in optoelectronic materials. Its structural rigidity in the excited state enhances quantum yield, making it suitable for use in luminescent devices and sensors.
