Used as a building block in metal-organic frameworks (MOFs), particularly for constructing porous materials with high thermal and chemical stability. Its rigid terphenyl backbone and carboxylic acid functional groups enable strong coordination with metal ions, facilitating the formation of extended network structures. These MOFs are explored for gas storage, separation processes, and catalysis due to their tunable pore size and surface area. The phenyl substituent enhances structural rigidity and influences the packing and porosity of the resulting framework.
