Used in organic electronics as a precursor for semiconducting polymers and small molecules in organic field-effect transistors (OFETs). Its stannyl groups enable efficient Stille coupling reactions, facilitating the synthesis of conjugated polymers for organic photovoltaics (OPVs) and light-emitting diodes (OLEDs). The rigid trans-ethene bridge enhances planarity and π-conjugation, improving charge carrier mobility. Commonly employed in research settings to develop high-performance, solution-processable electronic materials.
