This chemical is primarily used in the field of organic electronics and material science. It serves as a key precursor in the synthesis of conjugated polymers through carbon-carbon coupling reactions, such as the Stille coupling, which enables the formation of carbon-carbon bonds between organic compounds bearing alkyl, aryl, vinyl, or similar groups. These conjugated polymers are essential for developing organic semiconductors, widely applied in the fabrication of organic light-emitting diodes (OLEDs), organic photovoltaic cells (OPVs), and field-effect transistors (OFETs). Its role in polymer synthesis helps enhance the electrical conductivity and optical properties of the resulting materials, making it valuable for creating efficient and flexible electronic devices. Additionally, it is utilized in research to explore new materials with tailored electronic properties for advanced technological applications in materials chemistry and nanotechnology.
