Used as a brominated triarylamine intermediate for the synthesis of organic electronic materials. Commonly applied in OLED hole transport layers (HTL), organic photovoltaic materials, organic semiconductors, and photoelectric functional molecules. The bromine substituents provide reactive sites for further palladium-catalyzed cross-coupling reactions such as Suzuki-Miyaura coupling to prepare advanced conjugated materials.
