Application

2,5-Dibromo-3-octadecylthiophene is widely used in the synthesis of conjugated polymers for organic electronics, including organic field-effect transistors (OFETs) and photovoltaic devices. Its brominated thiophene core serves as a key monomer for polymerization via metal-catalyzed cross-coupling reactions. The long alkyl chain improves processability and film-forming properties in thin-film applications. Researchers also utilize this compound to study self-assembly and charge transport in supramolecular systems.
