Used as a multifunctional building block in the synthesis of porous organic frameworks, particularly covalent organic frameworks (COFs) and metal-organic frameworks (MOFs), due to its multiple aldehyde groups that enable Schiff base reactions. Its rigid terphenyl backbone and symmetrical aldehyde placements support the formation of highly ordered, stable, and porous network structures. These frameworks are applied in gas storage, selective adsorption, catalysis, and sensing technologies. The compound’s extended π-conjugation also makes it suitable for optoelectronic applications and as a precursor in designing functional nanomaterials.
