Used as a key building block in the synthesis of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), this compound enables the creation of highly porous and stable materials. Its rigid, extended π-conjugated structure supports the formation of ordered networks with large surface areas, making it valuable in gas storage, particularly for hydrogen and carbon dioxide. It is also employed in applications involving catalysis and chemical sensing due to its ability to coordinate with metal ions and its responsive structural framework. Additionally, its photophysical properties are exploited in optoelectronic devices and luminescent sensors.
