Metal Complex, Semiconductor Layer Comprising a Metal Complex and Organic Electronic Device

A metal complex of formula (I)

• wherein
• M is a metal ion;
• n is the valency of M and selected from 1 to 4;
• L has formula (II)
• R1 and R2 are independently selected from substituted or unsubstituted C1 to C12 alkyl, substituted or unsubstituted C6 to C19 aryl, substituted or unsubstituted C2 to C20 heteroaryl, or substituted or unsubstituted 6-membered heteroaryl;
• R3 is selected from substituted or unsubstituted C1 to C12 alkyl, substituted or unsubstituted C6 to C19 aryl, substituted or unsubstituted C2 to C20 heteroaryl, substituted or unsubstituted 6-membered heteroaryl, or CN;
• wherein
• at least one of the substituents of the substituted C1 to C12 alkyl, substituted C6 to C19 aryl, substituted C2 to C20 heteroaryl, or substituted 6-membered heteroaryl are independently selected from halogen, Cl, F, CN, partially or perfluorinated C1 to C8 alkyl, partially or perfluorinated C1 to C8 alkoxy;
• wherein
• at least one of R1, R2 and R3 or the group of R1, R2 and R3 comprises at least three atoms selected from the group consisting of halogen, Cl, F or N;
• wherein
• AL is an ancillary ligand which coordinates to the metal M;
• m is an integer selected from 0 to 2.
