Used as a hole-transporting material in organic light-emitting diodes (OLEDs), this compound helps improve device efficiency and stability. Its spirobifluorene-based structure provides good thermal stability and high glass transition temperature, making it suitable for use in high-performance OLED displays and lighting. The molecule’s twisted architecture prevents close packing, reducing aggregation and exciton quenching. It is particularly effective in blue-emitting OLEDs where charge balance and energy level alignment are critical. Also explored in perovskite solar cells as a dopant-free hole-transport layer to enhance device longevity and efficiency.
