Abstract

An organic molecule for use in optoelectronic components is disclosed having a structure of Formula I with X═CN or CF3, D= wherein # is the point of attachment of unit D to the central biphenyl in the structure according to Formula I; Z is a direct bond or is selected from the group consisting of CR3R4, C═CR3R4, C═O, C═NR3, NR3, O, SiR3R4, S, S(O), S(O)2; In each occurrence R1 is the same or different, is H, deuterium, a linear alkyl group having 1 to 5 C atoms, a linear alkenyl or alkynyl group having 2 to 8 C atoms, a branched or cyclic alkyl, alkenyl or alkynyl group having 3 to 10 C atoms, wherein one or more H atoms can be replaced by deuterium or an aromatic having 5 to 15 aromatic ring atoms, which can in each case be substituted with one or more radicals R6; and wherein at least one Ra is not H.
