Used as a key intermediate in organic semiconductors, particularly in the development of blue-emitting materials for OLED (organic light-emitting diode) devices. Its rigid, conjugated structure enhances electron transport and improves device efficiency. Commonly employed in host materials for phosphorescent OLEDs due to high triplet energy and thermal stability. Also utilized in perovskite solar cells as a hole-transporting layer component, contributing to improved power conversion efficiency and device longevity.
