Used as a building block in the synthesis of metal-organic frameworks (MOFs), particularly for gas storage and separation due to its extended aromatic structure that enhances framework stability and surface area. Also employed in the development of fluorescent sensors and optoelectronic materials because of its strong π-conjugation, which supports efficient light absorption and emission. Its rigid, planar structure makes it suitable for constructing porous polymers with tailored pore environments for catalysis or chemical sensing applications.
