Application

N,N'-Di-1-naphthyl-N,N'-diphenylbenzidine is a light yellow to yellow powder that serves as a highly effective hole-transporting material in OLED devices. Known also as NPB or NPD, this compound is widely utilized in OLEDs and other organic electronic devices, such as polymer photovoltaics (OPV) and perovskite solar cells, due to its exceptional ability to transport holes. NPB stands out among its competitors and is the most commonly used material in OLED applications. Its popularity is attributed to its increased glass transition temperature (Tg) of up to 95 °C, which improves device morphology and contributes to the longevity of the device.
