6-Bromo-2,2'-bipyridine is widely used in coordination chemistry as a ligand for constructing metal complexes. Its ability to bind with transition metals makes it valuable in catalysis, particularly in processes like cross-coupling reactions and polymerization. In materials science, it serves as a building block for creating organic electronic materials, such as light-emitting diodes (LEDs) and photovoltaic devices, due to its electron-accepting properties. Additionally, it is utilized in supramolecular chemistry for designing molecular architectures and frameworks. Its bromine atom also allows for further functionalization, enabling the synthesis of more complex derivatives for targeted applications.
