Organic electronic device comprising an anode layer, a cathode layer, at least one emission layer (eml) and at least one hole injection layer (hil)

An organic electronic device comprising an anode layer, a cathode layer, at least one emission layer (EML) and at least one hole injection layer (HIL), wherein the hole injection layer is arranged between the anode layer and the at least one emission layer, wherein

• the hole injection layer comprises an organic matrix compound (OMC) and a metal complex, wherein
• the organic matrix compound (OMC) and the emitter matrix compound (EMC) have the formula (I):
• wherein
• k, m, q, r are independently from each other 0, 1 or 2,
• p is 1, 2 or 3,
• wherein 2≤k+m+q+r+p≤11,
• Ar1 to Ar6 are independently selected from a substituted or unsubstituted unsaturated 5- to 7-member ring of a heterocycle, a substituted or unsubstituted C6 to C30 aryl or a substituted or unsubstituted C3 to C30 heteroaryl, a substituted or unsubstituted fluorene, or a fused ring system comprising 2 to 6 substituted or unsubstituted 5- to 7-member rings and the rings are selected from the group comprising (i) unsaturated 5- to 7-member ring of a heterocycle, (ii) 5- to 6-member of an aromatic heterocycle, (iii) unsaturated 5- to 7-member ring of a non-heterocycle, (iv) 6-member ring of an aromatic non-heterocycle;
• wherein the substituents are selected from the group H, D, C1 to C12 alkyl, unsubstituted C6 to C18 aryl, unsubstituted C3 to C18 heteroaryl, a fused ring system comprising 2 to 6 unsubstituted 5- to 7-member rings and the rings are selected from the group comprising unsaturated 5- to 7-member ring of a heterocycle, 5- to 6-member of an aromatic heterocycle, unsaturated 5- to 7-member ring of a non-heterocycle, and 6-member ring of an aromatic non-heterocycle;
• the metal complex has the formula (II):
• wherein
• M is a metal ion,
• n is the valency of M, wherein n is an integer from 1 to 4,
• L is a ligand;
• and wherein the organic matrix compound (OMC) and the emitter matrix compound (EMC) are selected the same or selected different.
