Application

N,N'-Di(1-naphthyl)-N,N'-diphenylbenzidine is primarily used as a hole transporting material in OLED devices, offering a light yellow to yellow powder form that is essential for its application. Known for its excellent hole transport capabilities, this material, also referred to as NPB or NPD, is utilized not only in OLEDs but also in various organic electronic devices, including polymer photovoltaics (OPV) and perovskite solar cells. Its effectiveness is highlighted by its superior competition, having become the most commonly used material in OLED applications. This widespread use is attributed to its increased glass transition temperature (Tg) of up to 95 °C, which improves device morphology and contributes to prolonged device lifespan.
