Used primarily as a monomer in the synthesis of conjugated polymers for organic electronics. It is especially valuable in the development of organic field-effect transistors (OFETs) and organic photovoltaics (OPVs) due to its ability to enhance polymer solubility and improve charge carrier mobility. The branched alkyl side chain helps in achieving better film morphology and thermal stability in thin-film devices. Its structural compatibility with various donor-acceptor copolymer systems makes it suitable for tuning optoelectronic properties in semiconductor materials.
