Used as a key intermediate in organic semiconductor materials, particularly in the production of blue-emitting layers for OLED (organic light-emitting diode) devices. Its rigid, conjugated structure enhances hole transport and improves device efficiency and stability. Commonly employed in host materials for phosphorescent OLEDs due to its high triplet energy level. Also utilized in the synthesis of polymers and small molecules for optoelectronic applications, including organic photovoltaics and field-effect transistors.
