Used as a key intermediate in the synthesis of conjugated polymers for organic electronics, particularly in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its alkyl side chain enhances solubility in organic solvents, facilitating solution-processing techniques like spin coating and inkjet printing. The bromine atom allows for further functionalization via cross-coupling reactions, such as Stille or Suzuki coupling, enabling the construction of complex conjugated systems. Commonly employed in the development of semiconducting materials with tunable electronic properties.
