Used as a chelating ligand in coordination chemistry, particularly in the formation of metal complexes with transition metals such as iron, copper, and zinc. Its tridentate structure allows for strong binding through nitrogen donor atoms, making it valuable in catalysis and sensor design. Employed in the development of luminescent materials and molecular devices due to its ability to enhance electronic, optical, and magnetic properties when bound to metal centers. Also investigated in supramolecular chemistry for constructing molecular switches and networks. Shows potential in electrochemical applications, including molecular electronics and redox-active systems.
