Used in organic electronics, particularly as a building block in the synthesis of high-performance organic semiconductors. It is commonly employed in the development of organic light-emitting diodes (OLEDs), where it serves as a key intermediate in hole-transport materials or host materials for blue phosphorescent OLEDs. Its rigid carbazole core and nitrile group enhance thermal stability and electron transport properties, making it suitable for use in advanced display technologies and solid-state lighting. Additionally, it finds application in photovoltaic cells and as a dopant in emissive layers to improve device efficiency and longevity.
