摘要： The present invention relates to an electronic device comprising a hole injection layer and/or a hole transport layer and/or a hole generating layer, wherein at least one of the hole injection layer, the hole transport layer and the hole generating layer comprises a coordination complex comprising at least one electropositive atom M having an electro-negativity value according to Allen of less than 2.4 and at least one ligand L having the following structure:




wherein R1 and R2 are independently selected from the group, consisting of C1 to C30 hydrocarbyl groups and C2 to C30 heterocyclic groups, wherein R1 and/or R2 may optionally be substituted with at least one of CN, F, Cl, Br and I.
