Used as a key intermediate in the synthesis of advanced organic materials, particularly in the preparation of metal-organic frameworks (MOFs) due to its ability to chelate metal ions through multiple oxygen donor sites. Its rigid aromatic structure and functional group arrangement make it suitable for constructing porous frameworks with high thermal and chemical stability. Also employed in the development of fluorescent sensors and optoelectronic materials, where its conjugated system contributes to tunable luminescent properties. Additionally, it serves as a building block in the design of functional polymers and coordination networks for catalytic applications.
