Used as a multifunctional linker in metal-organic frameworks (MOFs) due to its four carboxylic acid groups, enabling the construction of highly porous and stable network structures. Its rigid terphenyl units provide structural integrity and extended conjugation, making it suitable for applications in gas storage, catalysis, and sensing. The ethene core allows for electronic communication between the aromatic systems, enhancing performance in optoelectronic materials and molecular electronics. Also explored in supramolecular chemistry for designing complex architectures with precise geometry and functionality.
