UDSEENDE Lysegul-grønt pulver
N,N′-Di(1-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4′-diamine, also known as NPB or NPD, has been used intensively in OLEDs and other organic electronic devices such as polymer photovoltaics (OPV) and perovskite solar cells for its outstanding hole transport capability.
NPB is considered as one of the best materials within its competition, and has become the most common-used material in OLEDs’ application. This is due to its increased Tg up to 95 °C, which enhances device morphology and is beneficial for device longevity.
