Used as a key intermediate in the synthesis of high-performance organic semiconductors, particularly in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its extended π-conjugated structure enhances charge carrier mobility and light absorption properties. The aldehyde group allows for further functionalization via cross-coupling or condensation reactions, enabling fine-tuning of electronic properties. Commonly employed in donor-acceptor type polymers and small molecules for flexible electronics and printed semiconductor devices. Shows promise in improving device efficiency and stability due to its planar backbone and alkyl side chain solubilization.
