Used in organic electronics as a precursor for high-performance semiconducting materials. It plays a key role in the synthesis of conjugated polymers and small molecules for organic field-effect transistors (OFETs), offering good charge carrier mobility and film stability. Its tin-functionalized structure allows for efficient Stille coupling reactions in polymerization processes, enabling the fabrication of thin-film transistors and flexible electronic devices. Also explored in research for organic photovoltaics due to its extended π-conjugation and tunable electronic properties.
