Used as a linker in metal-organic frameworks (MOFs) due to its rigid aromatic structure and carboxylic acid functional groups. The compound enables the construction of porous materials for gas storage, particularly carbon dioxide and methane, owing to its ability to form extended networks with metal ions. Its conjugated backbone also supports applications in optoelectronic materials and sensors. Additionally, the methoxy groups can be modified for post-synthetic tuning of framework properties, enhancing performance in catalysis and selective adsorption.
