Used as a building block in coordination chemistry, particularly in the synthesis of metal-organic frameworks (MOFs) and catalysts. Its structure allows it to act as a bridging ligand, forming stable complexes with transition metals. These complexes are applied in catalytic reactions, including oxidation and coupling reactions. Also explored in photoluminescent materials and sensors due to its ability to chelate metals with optical activity. Additionally, derivatives are investigated for use in electroactive materials and organic electronics.
