We report highly efficient tandem OLEDs with novel electron transporting materials. Our electron transporting materials have very good electron transport and charge generation characteristics. As a result, fabricated phosphorescent red two stack tandem OLED device showed very low driving voltage of 5.0V, high EQE of 53.1%, and high power efficiency of 49.3lm/W.
