Abstract

The present invention relates to an electronic device comprising between a first electrode and a second electrode at least one first hole transport layer (7), wherein the first hole transport layer comprises (i) at least one first hole transport matrix compound consisting of covalently bound atoms and (ii) at least one electrical p-dopant selected from metal salts and from electrically neutral metal complexes comprising a metal cation and a at least one anion and/or at least one anionic ligand consisting of at least 4 covalently bound atoms, wherein the metal cation of the electrical p-dopant is selected from alkali metals; alkaline earth metals, Pb, Mn, Fe, Co, Ni, Zn, Cd; rare earth metals in oxidation state (II) or (III); Al, Ga, In; and from Sn, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W in oxidation state (IV) or less; provided that a) p-dopants comprising anion or anionic ligand having generic formula (Ia) or (Ib) wherein A 1 , A 2 , A 3 and A 4 are independently selected from CO, SO 2 or POR 1 ; R 1 = electron withdrawing group selected from the group comprising halide, nitrile, halogenated or perhalogenated C 1 to C 20 alkyl, halogenated or perhalogenated C 6 to C 20 aryl, or halogenated or perhalogenated heteroaryl with 5 to 20 ring-forming atoms; B 1 , B 2 , B 3 and B 4 are same or independently selected from substituted or unsubstituted C 1 to C 20 alkyl, substituted or unsubstituted C 1 to C 20 heteroalkyl, substituted or unsubstituted C 6 to C 20 aryl, substituted or unsubstituted C 5 to C 20 heteroaryl, or B 1 and B 2 form a ring; and b) p-dopants consisting of Li cation and an anion selected from perchlorate and tetrafluoroborate are excluded, and a method for preparing the same.
