Used as a key intermediate in the synthesis of high-performance polymers and specialty resins. Its rigid aromatic structure and functional groups make it suitable for creating heat-resistant and chemically stable polyesters and polyamides. Commonly applied in advanced coating materials and electronic encapsulants where thermal stability and mechanical strength are critical. Also investigated for use in metal-organic frameworks (MOFs) due to its ability to act as a bridging ligand, enabling the construction of porous materials for gas storage or catalysis. Its photophysical properties support applications in fluorescent sensors and optoelectronic devices.
