Used in organic synthesis as a fluorescent building block for the preparation of pyrene-based dyes and sensors. Its strong fluorescence and planar structure make it suitable for developing chemosensors that detect metal ions or small molecules. Also employed in the fabrication of organic semiconductors and optoelectronic materials due to its extended aromatic system. Commonly used in research for labeling biomolecules and studying molecular interactions via fluorescence spectroscopy. Additionally, serves as a precursor in the synthesis of liquid crystals and functional polymers with photoresponsive properties.
