Used primarily as an intermediate in the synthesis of conjugated polymers for organic electronics. It serves as a key building block in the preparation of semiconducting materials used in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). The presence of both bromo and iodo functional groups allows for selective cross-coupling reactions, such as Suzuki or Stille couplings, enabling controlled polymerization and precise chain architecture. The n-octyl side chain enhances solubility in organic solvents, facilitating solution processing and thin-film fabrication. Its structural features contribute to improved charge carrier mobility and film morphology in active layers of electronic devices.
