Used as a key ligand in coordination chemistry, particularly in the formation of metal complexes for catalytic applications. Its structure allows strong binding with transition metals, making it valuable in designing catalysts for organic transformations such as oxidation, reduction, and C–C bond formation. Also employed in the development of photochemical devices, including dye-sensitized solar cells and luminescent sensors, due to its ability to stabilize metal-to-ligand charge transfer states. Commonly used in supramolecular chemistry for constructing molecular machines, grids, and polymers with specific structural and electronic properties. Its ester group enables further functionalization, facilitating integration into larger molecular systems or surfaces for advanced materials research.
