Used in organic electronics, particularly as a hole-transport material in the development of organic light-emitting diodes (OLEDs), due to its strong fluorescence, good charge transport properties, thermal stability, and efficient π-π stacking enabled by its rigid, planar structure and delocalized electron system. This promotes ordered molecular arrangement in thin films, enhancing device efficiency and performance in high-performance semiconductor materials. Also investigated as a core structure in photovoltaic materials, fluorescent sensors for detecting specific ions or biomolecules, and as an intermediate in pharmaceutical development owing to its similarity to bioactive carbazole compounds.
