Used primarily in organic electronics, this compound serves as a key building block in the synthesis of conjugated polymers for organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its extended π-conjugated structure enhances charge carrier mobility, making it valuable in high-performance semiconductor materials. The bromine functional groups allow for efficient coupling reactions, such as Stille or Suzuki, enabling polymerization with various electron-rich or electron-deficient comonomers. Additionally, the alkyl side chain improves solubility in organic solvents, facilitating solution processing for thin-film device fabrication. Its incorporation into donor-acceptor type polymers helps fine-tune energy levels and optical properties, contributing to improved device efficiency and stability.
