Used as a highly selective fluorescent sensor for detecting metal ions, particularly aluminum and iron, in environmental and biological samples. Its extended aromatic structure enables strong fluorescence emission upon binding to specific cations, making it valuable in chemosensor design. Also applied in supramolecular chemistry to construct metal-organic frameworks (MOFs) due to its rigid, multi-dentate structure. Additionally, serves as a building block in the synthesis of porous organic materials for gas adsorption and separation processes.
