    • The present invention relates to an organic electronic device comprising, between an anode and a cathode, at least one layer selected from an electron injection layer, an electron transport layer or an electron generation layer, the layer comprising at least one compound of the following Formula (I):


      wherein the compound of Formula (I) comprises one or more moieties -(A) a -L and the remaining positions marked with "*" are hydrogen or substituents independently selected from the group consisting of deuterium, fluorine, RF, C 1 -C 20 linear alkyl, C 3 -C 20 branched alkyl, C 1 -C 12 linear fluorinated alkyl, CN, RCN, C 6 -C 20 aryl, C 2 -C 20 heteroaryl, (P=O)R 2 ; wherein each R is independently selected from C 1 -C 20 linear alkyl, C 1 -C 20 alkoxy, C 1 -C 20 thioalkyl, C 3 -C 20 branched alkyl, C 3 -C 20 cyclic alkyl, C 3 -C 20 branched alkoxy, C 3 -C 20 cyclic alkoxy, C 3 -C 20 branched thioalkyl, C 3 -C 20 cyclic thioalkyl, C 6 -C 20 aryl and C 2 -C 20 heteroaryl; A is selected from substituted or unsubstituted C 6 -C 24 aryl or C 2 -C 20 heteroaryl; wherein in case that A is substituted, the respective substituents are independently selected from the group consisting of deuterium, fluorine, C 1 -C 20 linear alkyl, C 3 -C 20 branched alkyl, linear fluorinated C 1 -C 12 alkyl, CN, C 6 -C 20 aryl, and C 2 - C 20 heteroaryl; L is selected from substituted or unsubstituted C 2 -C 42 heteroaryl, substituted or unsubstituted C 6- C 24 aryl or a polar group selected from

      wherein substituents, if present in the respective group L are independently selected from the group consisting of deuterium, fluorine, C 1 -C 20 linear alkyl, C 3 -C 20 branched alkyl, C 3 -C 20 cyclic alkyl, C 1 -C 20 linear alkoxy, C 3 -C 20 branched alkoxy, C 1 - C 12 linear fluorinated alkyl, C 1 -C 12 linear fluorinated alkoxy, C 3 -C 12 branched fluorinated cyclic alkyl, C 3 -C 12 fluorinated cyclic alkyl, C 3 -C 12 fluorinated cyclic alkoxy, CN, RCN, C 6 -C 20 aryl, C 2 -C 20 heteroaryl, OR, SR, (C=O)R, (C=O)NR 2 , SiR 3 , (S=O)R, (S=O) 2 R, (P=O)R 2 ; wherein each R independently selected from C 1 -C 20 linear alkyl, C 1 -C 20 alkoxy, C 1 -C 20 thioalkyl, C 3 -C 20 branched alkyl, C 3 -C 20 cyclic alkyl, C 3 -C 20 branched alkoxy, C 3 -C 20 cyclic alkoxy, C 3 -C 20 branched thioalkyl, C 3 -C 20 cyclic thioalkyl, C 6 -C 20 aryl and C 2 -C 20 heteroaryl, and "a" is an integer from o to 2, respective compounds as well as display and lightning devices comprising the same.
