Used as a key building block in the synthesis of metal-organic frameworks (MOFs), particularly for constructing porous materials with high thermal and chemical stability. Its rigid terphenyl backbone and multiple carboxylic acid groups enable strong coordination with metal ions, facilitating the formation of extended network structures. These MOFs find applications in gas storage, selective gas separation (such as CO₂/N₂ or CH₄/H₂), and catalysis due to their tunable pore environments. Additionally, the compound’s aromatic structure supports applications in luminescent materials and sensors, where it can act as an antenna ligand to enhance photophysical properties in lanthanide-based complexes.
