Used in the synthesis of metal-organic frameworks (MOFs) due to its multiple carboxylic acid groups and extended aromatic structure. The compound acts as a rigid, multitopic linker, enabling the formation of porous and highly ordered network structures. These MOFs find applications in gas storage, selective gas separation, and catalysis. Its methoxy and phenyl groups enhance structural stability and influence pore environment polarity, making it suitable for tuning host-guest interactions. Additionally, the compound’s photophysical properties can be exploited in luminescent sensors and optoelectronic materials when coordinated with metal ions.
