Used as a key building block in the synthesis of metal-organic frameworks (MOFs), particularly for constructing porous and stable structures with extended conjugation. Its rigid, linear geometry and carboxylic acid end groups allow for strong coordination with metal ions, enabling the formation of highly ordered crystalline networks. These MOFs are explored for applications in gas storage, such as hydrogen and carbon dioxide capture, due to their high surface area and tunable pore size. Additionally, the compound’s conjugated backbone makes it suitable for use in optoelectronic materials and sensors where electron delocalization is important. It is also employed in supramolecular chemistry to design functional materials with specific recognition or catalytic properties.
