Used as a key monomer in the synthesis of conjugated polymers for organic electronics, particularly in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its structure supports effective π-π stacking and charge carrier mobility, enhancing device performance. The hexyl side chain improves solubility in common organic solvents, facilitating solution-processing techniques like spin coating and inkjet printing. Widely employed in research and development of flexible electronics and printable semiconductors.
