ABSTRACT:
A stacked organic electroluminescent device and a method of making such device is disclosed. The device comprises an anode, a cathode, at least two organic electroluminescent units disposed between the anode and the cathode, and a doped organic connector disposed between each adjacent organic electroluminescent unit wherein the organic electroluminescent unit comprises at least one organic hole-transporting layer and one organic electron-transporting layer. The doped organic connector comprises at least one n-type doped organic layer or one p-type doped organic layer, or combinations of layers thereof.
