Used as an intermediate in organic synthesis, particularly in the preparation of functional materials for optoelectronic devices such as organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its halogenated structure allows for further cross-coupling reactions, such as Suzuki coupling, enabling the construction of complex conjugated systems. Commonly employed in the development of hole-transport materials and host compounds in emissive layers due to its favorable thermal stability and electronic properties. Also utilized in research settings for synthesizing carbazole-based polymers and small molecules with tailored luminescent and charge-transport characteristics.
