N,N-Diphenylpyridin-4-amine as a bipolar core structure of high-triplet-energy host materials for blue phosphorescent organic light-emitting diodes.


High-triplet-energy bipolar host materials with both holetransport and electron-transport units in the molecular structure have been developed to improve the quantum efficiency of blue phosphorescent organic light-emitting diodes (PHOLEDs) through charge balance in the emitting layer. The use of the bipolar host materials enabled the fabrication of high… (More)
