The invention pertains to an organic molecule for the use in optoelectronic devices. The organic molecule has a structure of formula (I) wherein each ring A, B, C, D, E, and F independently represents an aromatic or heteroaromatic ring, each comprising up to 18 carbon atoms, and, in case of a heteroaromatic ring, 1 to 3 heteroatoms independently selected from N, O, S, and Se; each ring A, B, C, D, E, and F independently represents an aromatic ring with 5 to 18 carbon atoms or a heteroaromatic ring with 4 to 18 carbon atoms, and, 1 to 3 heteroatoms independently selected from N, O, S, and Se; one or more hydrogen atoms in each of the aromatic or heteroaromatic rings A, B, C, D, E, and F are optionally substituted by a substituent R1; two or more adjacent substituents R1 optionally form an aliphatic or aromatic carbocyclic or heterocyclic ring system comprising up to 30 carbon atoms, and, in case of a heterocyclic ring system, up to three heteroatoms independently selected from the group of N, O, S, and Se; wherein this ring system is fused to the adjacent ring A, B, C, D, E or F and is optionally substituted with one or more substituents R2; Y1 and Y2 are at each occurrence independently selected from the group of NR3, O, S, and Se; wherein, in case one or both of Y1 and Y2 is/are NR3, the one or the two substituents R3 optionally and independently bond to one or both of the adjacent rings A and B (for Y1 = NR3) or C and D (for Y2 = NR3) with the provision that a connecting atom or atom group linking R3 to the respective ring A, B, C, or D is in each case independently selected from Se and NRY; and at least one ring of A, B, C, D, E, and F is a heteroaromatic ring.
