Used as a key building block in the synthesis of conjugated porous polymers and metal-organic frameworks (MOFs), this compound enables the development of materials with high surface areas and extended π-conjugation. Its rigid, linear alkyne core combined with carboxylic acid functionalities allows for strong coordination with metal ions and integration into stable, porous network structures. These materials are explored for applications in gas storage, particularly hydrogen and carbon dioxide capture, due to their tunable pore environments. Additionally, the compound contributes to the design of photocatalytic systems and organic electronics, where efficient charge transport and light absorption are critical. Its structural rigidity also supports the formation of covalent organic frameworks (COFs) used in sensing and separation technologies.
