Application
N,N'-Di-1-naphthyl-N,N'-diphenylbenzidine (purified by sublimation) is a light yellow to yellow powder that serves as an effective hole transporting material for OLED devices. Widely recognized in the field of organic electronics under the name NPB or NPD, this compound is renowned for its exceptional hole transport properties. It is frequently employed in OLEDs and finds applications in polymer photovoltaics (OPV) and perovskite solar cells due to these capabilities. NPB is considered a leading material among its competitors, becoming the most commonly used material in OLED applications. Its popularity can be attributed to its high glass transition temperature (Tg) of up to 95 °C, which enhances device morphology and significantly contributes to the longevity of these devices.
