Used as a versatile tridentate ligand in coordination chemistry, particularly in the formation of transition metal complexes for catalytic applications. Its structure allows for strong chelation with metals, making it valuable in homogeneous catalysis, such as in cross-coupling reactions and oxidation processes. Also employed in the development of luminescent materials and sensors due to its ability to stabilize metal centers that exhibit photophysical properties. Additionally, it finds use in supramolecular chemistry for constructing metallosupramolecular architectures like grids and cages.
