Abstract

We report novel bipolar host materials for high efficiency red and green phosphorescent OLEDs (PHOLEDs). Phenyl moieties were inserted in a 4,4'-N,N'-dicarbazolebipheyl (CBP) compound to provide much easier electron injection and to increase electron mobility. The efficiency increase and voltage reduction by this modification were observed in red and green PHOLEDs. At a given constant luminance of 1000 cd/m², the power efficiency was enhanced at least by twenty percent in the general red and green PHOLED devices.
