Used as a ligand in coordination chemistry, particularly in the formation of metal complexes for catalytic applications. Its structure allows for strong binding to transition metals, enhancing the stability and activity of catalysts in reactions such as cross-coupling and hydrogenation. Also employed in the development of luminescent materials and sensors due to its ability to form complexes with lanthanides and other emissive metal ions. Shows potential in organic electronics and photovoltaic devices as a component in light-emitting complexes and dye-sensitized solar cells.
