Used as a key building block in the synthesis of metal-organic frameworks (MOFs) due to its multiple carboxylic acid groups and rigid aromatic structure. The fluorine substituents enhance framework stability and influence pore surface properties, making it suitable for gas adsorption and separation applications. It is also employed in the design of porous materials for catalysis and sensing, where the combination of fluorination and extended π-conjugation improves chemical resistance and electronic tunability. Its tetrahedral geometry supports the formation of three-dimensional network structures with high surface areas.
