Used as a ligand in coordination chemistry, particularly in catalysis and metal-organic frameworks. Its nitrogen donor sites enable strong binding to transition metals, making it valuable in the development of catalysts for organic transformations such as cross-coupling and oxidation reactions. Also employed in electrochemical applications, including sensors and redox-active materials, due to its ability to stabilize metal ions in various oxidation states. Additionally, derivatives are explored in photophysical studies and as components in luminescent complexes.
