4,4'-Bipyridine 1,1'-Dioxide is widely used in coordination chemistry as a bridging ligand to construct metal-organic frameworks (MOFs) and coordination polymers. Its ability to form stable complexes with metal ions makes it valuable in designing materials with specific structural and functional properties. In supramolecular chemistry, it is employed to create host-guest systems due to its ability to participate in non-covalent interactions. Additionally, it finds applications in catalysis, where it acts as a ligand to stabilize catalytic centers in various organic transformations. Its redox-active nature also makes it suitable for use in electrochemistry and the development of sensors. In materials science, it is utilized in the synthesis of luminescent and magnetic materials, contributing to advancements in optoelectronics and data storage technologies.
