2,2’-Binaphthalene-6,6’-dicarboxylic acid(CAT: R048894) is a rigid, polyaromatic dicarboxylic acid composed of two naphthalene units connected at the 2,2’-positions, with carboxylic acid groups at the 6,6’-positions. This compound is widely used in coordination chemistry, metal-organic frameworks (MOFs), and the development of chiral ligands due to its extended π-conjugated system and axial chirality. Its robust, planar structure allows for strong π–π stacking interactions and structural rigidity, which are advantageous in supramolecular assemblies and functional materials. The carboxylic acid groups offer reactive sites for esterification, amidation, or metal coordination, making it a versatile building block for advanced materials and catalysis.
