Used in organic semiconductor materials, particularly in the synthesis of conjugated polymers for organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its structure supports effective π-conjugation and charge transport, making it valuable in developing high-performance electronic devices. The alkyne group allows for further functionalization via click chemistry, enabling precise molecular engineering. Also employed in research settings to tune the optoelectronic properties of donor-acceptor type polymers.
