Used as a key building block in the synthesis of metal-organic frameworks (MOFs), particularly for applications in gas storage, separation, and catalysis. Its rigid terphenyl backbone and carboxylic acid functional groups allow for the formation of highly ordered porous structures with large surface areas. The presence of hydroxyl groups adds polarity and potential for hydrogen bonding, enhancing interactions with specific guest molecules. This makes the compound valuable in designing MOFs for selective CO₂ capture, sensing applications, and as a linker in functional porous materials for environmental and energy-related technologies.
