A power-efficient and stable organic light emitting diode with a simplified structure based on 2-methyl-9,10-di(2-naphthyl)anthracene (MADN) has been developed. The incorporation of 10% tungsten oxide (WO3) into MADN and 15% cesium carbonate (Cs2CO3) into MADN has been found to improve the hole and electron injection, respectively. Based on this work, it is anticipated that p-i-n OLEDs fabrication process can be considerably simplified and the bill of materials cost can reduced by using one ambipolar host for both the p-and n-doped carrier transport layers.
