Used as a fluorescent sensor for detecting metal ions, particularly copper(II) and iron(III), due to its strong emission properties that change upon binding. Also employed in supramolecular chemistry for constructing metal-organic frameworks and gels, where its rigid structure and multiple binding sites enhance stability and selectivity. Shows potential in bioimaging and environmental monitoring because of its sensitivity and selectivity in aqueous or mixed solvent systems. Additionally, investigated for use in optoelectronic devices as a component in light-emitting materials.
