Used as a key building block in organic semiconductors, especially in the production of OLEDs (organic light-emitting diodes) for displays and lighting. Its rigid aromatic structure enhances thermal stability and hole-transport properties, making it valuable in emissive and host materials within blue and green phosphorescent OLED devices. Also employed in the synthesis of pharmaceuticals and dyes due to its extended π-conjugated system, which supports tunable electronic properties. Commonly found in photoconductors and organic photovoltaics for improved charge transport efficiency.
