Used in organic electronics, particularly in the development of organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its bromine functional group allows for further chemical modifications via cross-coupling reactions, making it a valuable intermediate in synthesizing conjugated materials. The carbazole core provides good hole-transport properties and thermal stability, enhancing device performance. Commonly employed in the fabrication of efficient blue emitters and as a building block for host materials in emissive layers of OLEDs. Also utilized in perovskite solar cells as a component of hole-transport materials to improve efficiency and stability.
