Used as a key ligand in coordination chemistry, particularly in the development of catalytic systems for polymerization and cross-coupling reactions. Its vinyl groups enable covalent attachment to surfaces or polymers, making it valuable in designing functional materials for sensors and electrochemical devices. Often employed in the synthesis of metal-organic frameworks (MOFs) and supramolecular architectures due to its ability to chelate transition metals while offering sites for further chemical modification. Also explored in dye-sensitized solar cells and luminescent complexes owing to its electronic properties when bound to metal centers.
