Used as a key intermediate in the synthesis of organic semiconductors and optoelectronic materials, including organic thin-film transistors (OTFTs). Its brominated structure allows for further functionalization via cross-coupling reactions, making it valuable in the development of organic light-emitting diodes (OLEDs) and photovoltaic devices. The carbazole core combined with the benzoyl group enhances hole-transport properties and thermal stability, which are critical for high-performance electronic applications. The wide aromatic structure and bromine substituents help tune molecular energy levels (HOMO/LUMO) for efficient charge transport, along with good stability to light and air, making it suitable for durable thin films. Also explored in the design of fluorescent sensors and dyes due to its rigid, conjugated framework that supports strong emission characteristics. Additionally, it serves as a photoinitiator in UV-curable resin systems, as the benzoyl group absorbs UV radiation and generates free radicals efficiently.
