Method for producing an organic electronic component
A method for producing an organic electronic component. According to the method, an anode is provided. A first layer is applied to the anode, which acts in a hole injecting manner and has a first matrix material and a dopant embedded therein. The dopant is a p-type dopant having at least one material which has a lewis acidity at least partially or completely with regard to the matrix material. A second layer is applied to the first layer, the second layer acts in a hole-transporting manner to the first layer which acts in a hole-transporting manner. At least one light-emitting layer is applied to the second layer. A cathode is applied to the light-emitting layer.
1 . A method for producing an organic electronic component comprising the steps of:
A) providing an anode,
B) applying a first layer to the anode, wherein the first layer has a first matrix material and a dopant embedded therein,
wherein the dopant is a p-type dopant comprising at least one material which has a lewis acidity completely with regard to the matrix material,
C) applying a second layer to the first layer wherein the second layer has a second matrix material, wherein the first layer is arranged between the first layer and the anode, wherein a thickness of the second layer is greater than a thickness of the first layer,
D) applying at least one light-emitting layer to the second layer, wherein the second layer is arranged between the anode and the at least one light emitting layer; and
E) applying a cathode to the at least one light-emitting layer such that the light-emitting layer is arranged between the anode and the cathode.
2 . The method according to claim 1 ,
wherein the first layer is produced by co-deposition of the matrix material and of the dopant via physical vapour deposition.
3 . The method according to claim 1 ,
wherein the first layer is produced by means of a wet-chemical method.
4 . The method according to claim 1 ,
wherein the second layer is produced by means of physical vapor deposition or a wet chemical method.
