Used as a key monomer in the synthesis of high-performance polymers, particularly in the production of polyesters and polyamides with enhanced thermal stability and mechanical strength. Its rigid, planar structure contributes to the formation of materials suitable for advanced engineering plastics and optoelectronic applications. Also employed in the development of metal-organic frameworks (MOFs) due to its ability to chelate metal ions, enabling applications in gas storage, catalysis, and sensing. Additionally, serves as a building block in conjugated organic frameworks for use in organic semiconductors and photovoltaic devices.
