Used as a key intermediate in the synthesis of conjugated polymers for organic electronics, particularly in organic photovoltaics (OPVs) and organic field-effect transistors (OFETs). Its aldehyde functional groups allow for easy extension of the π-conjugated system via cross-coupling or condensation reactions, enabling fine-tuning of electronic properties. It is also employed in the development of organic semiconductors due to its strong light absorption and charge transport characteristics. Additionally, it serves as a building block for push-pull type polymers when reacted with electron-rich or electron-deficient comonomers.
