Used as a ligand in coordination chemistry, it forms stable complexes with various metal ions, particularly transition metals, enhancing their catalytic properties in organic synthesis. It is employed in the development of luminescent materials due to its ability to create highly emissive metal complexes, useful in optical sensors and light-emitting devices. Additionally, it serves as a key component in the synthesis of advanced materials for photophysical and electrochemical studies, aiding in the design of efficient catalysts and functional materials. Its role in stabilizing metal centers also makes it valuable in bioinorganic chemistry for modeling metalloenzyme active sites.
