Used primarily as an intermediate in the synthesis of advanced organic semiconductors, this compound plays a key role in the development of conjugated polymers for organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its extended π-conjugated structure enhances charge carrier mobility and stability in electronic devices. The nonyl chain improves solubility in organic solvents, facilitating solution-based processing techniques like spin coating or inkjet printing. It is also explored in the design of semiconducting materials for flexible electronics and wearable sensors due to its favorable thermal and oxidative stability.
