Used as a key intermediate in organic semiconductors, especially in the production of blue-emitting materials for OLED (organic light-emitting diode) devices. Its carbazole moiety provides good hole-transport properties, making it valuable in display technologies and lighting panels. Commonly found in host or dopant materials within emissive layers, it contributes to high efficiency and stability in electroluminescent applications. Also employed in the synthesis of advanced materials for photovoltaic cells and field-effect transistors due to its excellent thermal and electrochemical stability.
