The present invention relates to compound represented by Formula (I)
wherein M is a metal; L is a charge-neutral ligand, which coordinates to the metal M; n is
an integer selected from 1 to 4, which corresponds to the oxidation number of M; m is an integer selected from 0 to 2; R1, R2 and R3 are substituents; at least one
R1, R2 and/or R3 is selected from a substituted C2 to C24 heteroaryl group, wherein at least one substituent is selected from halogen, F, CI, CN, partially or fully fluorinated C1 to C6 alkyl, partially or fully fluorinated C1 to C6 alkoxy.
The present invention also relates to a semiconductor material comprising at least one compound of formula (I), an semiconductor layer comprising at least one compound of formula (I) and an electronic device comprising at least one compound of formula (I).
Exemplary compounds are e.g. metal complexes of 3-(2,3,5-trifluoro-6-(trifluoromethyl)pyridin-4-yl)pentane-2,4-dione, such as e.g. tris(((Z)-4-oxo-3-(2,3,5-trifluoro-6-(trifluoromethyl)pyridin-4-yl)pent-2-en-2-yl)oxy)
