Application

This compound serves as a key precursor in the synthesis of fluorinated conjugated polymers for organic photovoltaic (OPV) devices and field-effect transistors (OFETs). Its dual stannane functionality enables efficient Stille cross-coupling reactions with various aryl halides. The fluorine substitution enhances electronic properties while maintaining processability. Researchers utilize it to develop novel semiconducting materials with tailored HOMO-LUMO levels. Particularly valuable for creating donor-acceptor copolymers in bulk heterojunction solar cells.
