Used primarily as an intermediate in the synthesis of conjugated polymers for organic electronics. It plays a key role in the development of organic semiconductors used in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). The compound’s thiophene backbone and electron-withdrawing nitrile group enhance charge carrier mobility and stability in thin-film devices. Its solubilizing 2-ethylhexyloxy side chain improves processability in solution-based fabrication techniques, making it suitable for printable electronics and flexible solar cells. Also investigated for use in organic light-emitting diodes (OLEDs) due to its favorable electronic properties.
