Used primarily as a key intermediate in the synthesis of conjugated polymers for organic electronics. It serves as a monomer in the preparation of high-performance organic semiconductors used in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). The branched alkyl chain enhances solubility in organic solvents, facilitating solution-processing techniques like spin-coating and inkjet printing. Its structural design promotes strong π-π stacking and improved thin-film morphology, contributing to higher charge carrier mobility. Also employed in the development of donor-acceptor copolymers to tune energy levels and optical absorption properties for efficient solar cells.
