Used as a ligand in coordination chemistry to form stable complexes with transition metals, enhancing catalytic activity in various organic reactions. Applied in the synthesis of metal-organic frameworks (MOFs) for gas storage and separation. Utilized in the development of electrochemical sensors for detecting metal ions due to its chelating properties. Employed in photochemical studies for designing light-harvesting materials and photocatalysts. Also serves as a building block in the preparation of supramolecular structures for advanced material applications.
