Abstract

Specific polycyclic compounds of the general formula (I) and a process for their preparation, a material for an organic electroluminescence device comprising said compound, an organic electroluminescence device comprising said compound, an electronic equipment comprising said organic electroluminescence device, and the use of compounds according to general formula (I) in an organic electroluminescence device.

Claims (9)

1 . An organic electroluminescence device, comprising:

a cathode;

an anode; and

an organic thin film between the cathode and the anode,

wherein

the organic thin film comprises a light emitting layer, and at least one other layer,

the at least one other layer of the organic thin film comprises an electron transporting layer between the cathode and the light emitting layer or a hole blocking layer and an electron layer is between the electron transporting layer and the light emitting layer, the at least one other layer comprises a layer is between the electron transporting layer, the at least one other layer comprises a compound, and the light emitting layer does not comprise the compound, wherein the compound is selected from the group consisting of Compounds 1, 3, and 6 to 17:

2 . The organic electroluminescence device according to claim 1 , wherein the at least one other layer of the organic thin film comprises an electron transporting layer between the cathode and the light emitting layer and the electron transporting layer comprises the compound.

3 . The organic electroluminescence device according to claim 1 , wherein the at least one other layer of the organic thin film comprises a hole blocking layer and an electron transporting layer between the cathode and the light emitting layer, where the hole-blocking layer is between the electron transporting layer and the light emitting layer, and the hole blocking layer comprises the compound.
