Used as a chelating agent in coordination chemistry, particularly in the formation of metal-organic frameworks (MOFs) due to its rigid structure and multiple binding sites. Its extended aromatic system enhances stability and electronic properties in supramolecular assemblies. Employed in catalysis, especially in reactions requiring bidentate ligands with nitrogen and oxygen donor atoms. Also investigated for applications in luminescent materials and sensors owing to its ability to form complexes with lanthanide and transition metals that exhibit unique photophysical behavior. Its structural rigidity makes it suitable for designing porous materials with tailored functionality.
