Used in organic light-emitting diodes (OLEDs) as an intermediate for electron-transport materials due to the nitrile group’s electron-withdrawing properties. The trimethylsilyl-protected ethynyl group allows for controlled coupling reactions in the synthesis of conjugated organic semiconductors. Employed in solution-processable emissive layer fabrication, where its silyl group enhances solubility and film uniformity. Also applied in cross-coupling reactions such as Sonogashira to build extended π-conjugated systems for optoelectronic devices. Shows potential in fluorescent sensors and as a building block in metal-organic frameworks with luminescent properties.
