Used as a key intermediate in organic semiconductor materials, particularly in the development of blue-emitting layers for OLED (organic light-emitting diode) devices. Its rigid carbazole structure enhances hole transport properties and thermal stability, making it valuable in high-performance optoelectronic applications. Also employed in host materials for phosphorescent OLEDs due to its high triplet energy level. Additionally, it serves as a building block in the synthesis of conjugated polymers and dendrimers for use in organic photovoltaics and sensors.
