Used as a key intermediate in the synthesis of organic semiconductors, particularly in the development of high-performance n-type and ambipolar organic field-effect transistors (OFETs). Its rigid, planar structure and strong electron-withdrawing cyano groups enhance electron mobility and stability in thin-film transistor devices. Also employed in the preparation of conjugated polymers and small molecules for organic photovoltaics (OPVs) and perovskite solar cells, where it contributes to efficient charge transport. Additionally, it serves as a building block in the fabrication of organic light-emitting diodes (OLEDs) and sensors due to its tunable electronic properties.
