Used as a ligand in coordination chemistry, 2,4'-Bipyridine forms stable complexes with transition metals, making it valuable in catalysis and the development of metalloorganic compounds. It is employed in the synthesis of catalysts for organic transformations, including cross-coupling reactions and oxidation processes. Its structural configuration allows for selective metal binding, which is exploited in the design of functional materials and sensors. Additionally, derivatives of 2,4'-bipyridine are investigated for applications in photovoltaic systems and molecular electronics due to their electron-accepting properties and ability to participate in charge transfer interactions.
