Used as a ligand in coordination chemistry, particularly in the design of transition metal complexes for catalytic applications. Its structure allows for strong binding to metal centers, making it useful in homogeneous catalysis, such as in reactions involving C–H activation and cross-coupling transformations. Also employed in the development of luminescent complexes due to its ability to stabilize metal ions in specific oxidation states. Additionally, it serves as a building block in supramolecular chemistry for constructing molecular sensors and functional materials with tailored electronic properties.
