NBPhen, EIL and HBL material for OLEDs and photovoltaic devices
High-purity (>99.0%) and available online for priority dispatch
NBPhen, full name 2,9-Dinaphthalen-2-yl-4,7-diphenyl-1,10-phenanthroline, is one of the close relatives of BPhen, which is used in OLEDs and photovoltaic devices as an electron-injection layer or hole-blocking layer material. Due to its low evaporation temperature and air stability, caesium azide (CsN3) doped NBphen has also been demonstrated as an efficient electron-injection layer (EIL) capable of replacing lithium fluoride (LiF) in such devices.
OLEDs utilising CsN3 -doped NBPhen as EIL exhibit significantly improved current density-luminance-voltage characteristics.
*Sublimation is a technique used to obtain ultra pure-grade chemicals. For more details about sublimation, please refer to the sublimed Materials for OLED devices page.
