Used as a key intermediate in organic semiconductors, particularly in the synthesis of conjugated polymers for organic photovoltaics (OPVs) and organic field-effect transistors (OFETs). Its structure supports efficient π-conjugation and charge transport, enhancing device performance. The bromine groups allow for further functionalization via cross-coupling reactions, making it valuable in tailoring polymer properties. Commonly employed in donor-acceptor type copolymers to tune bandgap and improve light absorption in solar cells. Also utilized in research settings to develop high-mobility, solution-processable semiconducting materials for flexible electronics.
