Used primarily as a building block in the synthesis of metal-organic frameworks (MOFs), particularly in coordination polymers where its carboxylate groups bind to metal ions to form porous structures. These frameworks have applications in gas storage, separation, and catalysis. Also employed in the development of functional materials due to its rigid aromatic backbone and ability to direct specific network topologies. The methoxy group enhances solubility and influences electronic properties, making it useful in designing luminescent MOFs or sensors. Additionally, it serves as a linker in polymers for advanced materials with tailored porosity and stability.
