Used as an intermediate in the synthesis of high-performance organic semiconductors and optoelectronic materials. Its rigid aromatic structure and electron-withdrawing nitrile groups make it suitable for constructing conjugated polymers and small molecules in organic field-effect transistors (OFETs) and organic light-emitting diodes (OLEDs). Also employed in the development of fluorescent dyes and sensors due to its ability to participate in π-π stacking and charge-transfer interactions. Additionally, it serves as a building block in pharmaceuticals and agrochemicals where fused aromatic systems with polar functional groups are required.
