Used as a key intermediate in the synthesis of conjugated polymers for organic electronics. It enables the preparation of high-performance organic semiconductors used in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). The compound’s stannane groups facilitate Stille coupling reactions, allowing efficient incorporation into complex polymer chains with good regioregularity and electronic properties. Its structure supports extended π-conjugation, enhancing charge carrier mobility in thin-film devices. Commonly employed in research and development of solution-processable electronic materials.
