| abstract |
The invention relates to an organic molecule, especially for use in optoelectronic components. According to the invention, the organic molecule has a structure of formula (I) wherein X = CN or CF 3 , D = formula (II) wehrein # is the attachment point 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 CR 3 R 4 , C=CR 3 R 4 , C=O, C=NR 3 , NR 3 , O, SiR 3 R 4 , S, S(O), S(O) 2 ; R 1 is the same or different at each instance and can represent H, deuterium, a linear alkyl group having 1 - 5 carbon atoms, a linear alkenyl or alkynyl group having 2 - 8 carbon atoms, a branched or cyclic alkyl, alkenyl or alkynyl group having 3 - 10 carbon atoms, wherein one or more hydrogen atoms can be replaced by deuterium, or an aromatic with 5 - 15 aromatic ring atoms that can be substituted in each case by one or more R 6 radicals; and wherein R a is different to H. |
