Used as a key intermediate in the synthesis of advanced polyimides and polyamides, offering enhanced thermal stability and mechanical strength for high-performance materials. Its extended aromatic structure improves charge transport properties, making it suitable for organic semiconductors and optoelectronic devices such as OLEDs and organic photovoltaics. Also employed in the development of covalent organic frameworks (COFs) due to its rigid, planar geometry and multiple reactive sites, enabling applications in gas storage, catalysis, and sensing. Shows potential in fluorescent probes and sensors owing to its strong π-conjugation and tunable emission characteristics.
