Application

This compound serves as a key intermediate in synthesizing low-bandgap polymers for organic photovoltaics (OPVs), where its electron-accepting DPP core enhances charge transport. The bromothiophene moiety enables further functionalization via cross-coupling reactions (e.g., Suzuki, Stille), while the aldehyde group allows condensation reactions for ??-extension. Researchers utilize it to develop near-infrared (NIR) absorbers and high-mobility semiconductors for flexible electronics.
