An electron transporting-injection compound, represented by following Formula
- wherein each of the R1, the R2 and the R3 is selected from substituted or non-substituted aromatic group, substituted or non-substituted heterocyclic group, or of substituted or non-substituted aliphatic group, and at least one of the R2 and the R3 is selected from substituted or non-substituted heterocyclic group.
An electron transporting-injection compound, represented by following Formula 1:
- wherein each of the R1, the R2 and the R3 is selected from substituted or non-substituted aromatic group, substituted or non-substituted heterocyclic group, or of substituted or non-substituted aliphatic group, and at least one of the R2 and the R3 is selected from substituted or non-substituted heterocyclic group.
An organic electroluminescent device, comprising:
- a first electrode;
- a second electrode facing the first electrode;
- and
- an organic emitting layer positioned between the first and second electrodes and including a hole injection layer on the first electrode, a hole transporting layer on the hole injection layer, an emitting material layer on the transporting hole injection layer and an electron transporting-injection layer on the emitting material layer, wherein the electron transporting-injection layer formed of an electron transporting-injection compound represented by following Formula 1:
- wherein each of the R1, the R2 and the R3 is selected from substituted or non-substituted aromatic group, substituted or non-substituted heterocyclic group, or of substituted or non-substituted aliphatic group, and at least one of the R2 and the R3 is selected from substituted or non-substituted heterocyclic group.
