Used in organic light-emitting diodes (OLEDs) as a hole-transporting material due to its excellent thermal stability and efficient charge transport properties. Commonly employed in blue-emitting OLED devices to enhance device efficiency and lifetime. Also utilized as a building block in the synthesis of conjugated polymers for organic photovoltaics (OPVs), contributing to improved light absorption and energy level tuning. Its hexyl chain enhances solubility in organic solvents, facilitating solution-based device fabrication such as spin-coating or inkjet printing.
