Used as a key building block in organic semiconductors, particularly in the production of OLEDs (organic light-emitting diodes) for displays and lighting. Its rigid structure enhances thermal stability and improves charge transport in electronic devices. Commonly employed in host materials for blue phosphorescent OLEDs due to its high triplet energy level. Also utilized in perovskite solar cells as a hole-transporting material to increase efficiency and device stability. Suitable for use in various optoelectronic applications requiring durable and efficient organic matrices.
