Used in organic electronics, particularly in the development of organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs), due to its excellent hole-transport properties and thermal stability. Its derivative structures serve as key building blocks in host materials for blue phosphorescent OLEDs, enhancing device efficiency and lifespan. Also employed in the synthesis of pharmaceuticals and dyes, where the carbazole core contributes to biological activity and structural rigidity. Its methoxy substitution improves solubility and influences electronic properties, making it suitable for solution-processed electronic devices.
