Used in organic electronics as a building block for conjugated polymers and small molecules in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its brominated structure allows for further functionalization via cross-coupling reactions, enabling precise control over electronic properties. Commonly employed in the synthesis of semiconducting materials due to the electron-rich nature of the bithiophene core, enhancing charge transport characteristics. Also explored in dye-sensitized solar cells and as a component in donor-acceptor type polymers for improved light absorption and bandgap tuning.
