Used as a key building block in the synthesis of metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), this compound acts as a multitopic linker due to its four carboxylic acid groups and extended π-conjugated structure. Its rigid, planar geometry promotes the formation of highly ordered porous networks, making it valuable in gas storage, catalysis, and sensing applications. The nitrogen-rich aromatic core enhances electronic properties, enabling use in optoelectronic materials and organic semiconductors. Additionally, its ability to chelate metal ions supports applications in coordination polymers for environmental remediation, such as capturing heavy metals or toxic gases.
