Used as a key intermediate in organic semiconductors and optoelectronic materials. Commonly applied in the synthesis of conjugated polymers and small molecules for organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its electron-deficient character enhances charge transport properties in donor-acceptor type materials. Also employed in fluorescence-based sensors due to its ability to act as an electron acceptor in push-pull systems. Suitable for research in developing new organic electronic materials with tunable band gaps.
