  • Electron transport materials with selected dipole moments
    Patent number: 10074809
    Abstract: An exemplary embodiment of the present specification provides an organic electroluminescence device including: an anode; a cathode; a light emitting layer provided between the anode and the cathode; and an electron transporting layer provided between the cathode and the light emitting layer, in which the electron transporting layer includes a first electron transporting material and a second electron transporting material, the first electron transporting material is an organic material including a monocyclic or polycyclic ring which includes an N-containing six-membered ring, the second electron transporting material is an organic material including a five-membered hetero ring which includes at least one heteroatom of N, O, and S, or a cyano group, and a dipole moment of the second electron transporting material is larger than a dipole moment of the first electron transporting material.
