Used as a building block in coordination chemistry, particularly in the design of metal-organic frameworks (MOFs) and supramolecular architectures. Its multiple pyridine and ether functional groups enable strong and directional interactions with metal ions, facilitating the formation of porous and catalytically active materials. Commonly employed in the development of sensors and catalysts due to its ability to stabilize transition metal centers and promote selective binding of substrates. Also explored in photoactive complexes where ligand-to-metal charge transfer is utilized for light-harvesting applications.
