Used primarily as a key intermediate in the synthesis of conjugated polymers for organic electronics. Its stannyl groups enable efficient Stille coupling reactions, making it valuable in creating organic semiconductors for applications in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). The fluorine substituents enhance electron affinity and improve charge carrier mobility, contributing to better device performance. It is also employed in the development of thiophene-based copolymers with tunable electronic properties for use in flexible electronics and printable circuits.
