Used as a key intermediate in organic synthesis, particularly in the preparation of conjugated polymers and organic semiconductors. Its rigid, linear structure with bromine functional groups makes it ideal for cross-coupling reactions, such as Sonogashira and Suzuki couplings, enabling the construction of extended π-conjugated systems. Commonly employed in the development of organic electronic materials, including organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Also utilized in the synthesis of carbon-rich molecular wires and graphene-like nanostructures for advanced materials research.
