This chemical is primarily used as a ligand in coordination chemistry, where it forms stable complexes with various metal ions. Its ability to chelate metals makes it valuable in catalysis, particularly in organic synthesis and polymerization reactions. Additionally, it is employed in the development of supramolecular structures and materials, such as metal-organic frameworks (MOFs), due to its rigid bipyridine core and functional hydroxyl groups. In research, it serves as a building block for designing molecular sensors and probes, leveraging its metal-binding properties for detecting specific ions or molecules. Its applications also extend to the field of photochemistry, where it is used in the study of light-induced processes and the development of photoactive materials.
