Used as a highly selective ligand in coordination chemistry, particularly for binding transition metal ions in catalytic systems. Its rigid, symmetrical structure enhances stability in metal-organic frameworks (MOFs), making it valuable in designing porous materials for gas storage and separation. Also employed in luminescent complexes due to its ability to facilitate energy transfer in europium and terbium coordination compounds. Shows potential in optoelectronic applications and as a building block in supramolecular assemblies for sensor development.
