Used in organic electronics as a building block for synthesizing hole-transport materials and host compounds in OLEDs. Serves as an intermediate in the production of carbazole-based polymers and dendrimers for photovoltaic devices. Its bromoalkyl chain enables easy functionalization for cross-linking or attaching to other aromatic systems, enhancing thermal stability and film-forming properties in thin-film applications. Also employed in the development of fluorescent sensors and optoelectronic materials due to its strong luminescence and electron-donating characteristics.
