ORGANIC MOLECULES FOR OPTOELECTRONIC DEVICES

The invention relates to an organic molecule for optoelectronic devices. According to the invention, the organic molecule has: -a chemical moiety with a structure of formula I: and-one or two second chemical moieties with a structure of formula II: wherein RI, RII, RIII, RIV, RV, RVI, RVII, RVIII, RIX, and RX are at each occurrence independently selected from the group consisting of the binding site of a single bond linking the first chemical moiety to the second moiety, hydrogen, deuterium, OPh, SPh, CF3, CN, F, Si(C1-C5-alkyl)3, Si(Ph)3, C1-C5-alkyl, C1-C5-alkoxy, C1-C5-thioalkoxy, C2-C5-alkenyl, C2-C5-alkynyl, C6-C18-aryl, C3-C17-heteroaryl, N(C6-C18-aryl)2, N(C3-C17-heteroaryl)2; N(C3-C17-heteroaryl)(C6-C18-aryl); the dashed lines "Formula III" in formula II represent the binding sites of the first chemical moiety to the second chemical moiety; Z is at each occurrence independently selected from the group consisting of a direct bond, CR3R4, C═CR3R4, C═O, C═NR3, NR3, O, SiR3R4, S, S(O) and S(O)2; Ar1 is C6-C60-aryl, which is optionally substituted with one or more substituents R6; wherein either RV and RVI, or RVI and RVII represent the binding sites of a single bond linking the first chemical moiety to the second chemical moiety to form a ring.
