The invention pertains to an organic molecule for use in optoelectronic devices. According to the invention, the organic molecule has: - a first chemical moiety with a structure of formula (I), - one or two second chemical moieties with a structure of formula (II) wherein RZ is at the binding site of a single bond linking the first chemical moiety to the second moiety; RY is at the binding site of a single bond linking the first chemical moiety to the second moiety or Ra; and the dashed lines (a) represent the binding sites of the first chemical moiety to the second chemical moiety.
