Used as a key intermediate in the synthesis of advanced organic semiconductors and optoelectronic materials. Its strong electron-withdrawing nature due to the tricarbonitrile group enhances charge transport properties in organic thin-film transistors (OTFTs) and dye-sensitized solar cells (DSSCs). Also employed in the development of near-infrared (NIR) dyes and fluorescent probes for bioimaging, thanks to its extended π-conjugation and tunable absorption. Shows promise in nonlinear optical (NLO) materials for photonic devices.
