Application

4,4′-Dimethyl-2,2′-bipyridine is commonly employed as a chelating ligand in transition metal catalysis, particularly in ruthenium-based photoredox catalysts for organic synthesis. It also serves as a key component in dye-sensitized solar cells (DSSCs) due to its electron-transfer properties. Researchers utilize it in supramolecular chemistry to construct metal-organic frameworks (MOFs) and other functional materials.
