The invention relates to an organic molecule, in particular for use in organic optoelectronic devices. According to the invention, the organic molecule consists of
a first chemical moiety with a structure of formula I,
and
two second chemical moieties, each at each occurrence independently from another, with a structure of formula II,
wherein the first chemical moiety is linked to each of the two second chemical moieties via a single bond;
wherein
T, V is independently from another the binding site of a single bond linking the first chemical moiety to one of the two second chemical moieties or is hydrogen;
W, X, Y is independently from another the binding site of a single bond linking the first chemical moiety to one of the two second chemical moieties or is selected from the group consisting of hydrogen, CN and CF
3
;
wherein exactly one substituent selected of the group consisting of W, X, and Y is CN or CF
3
, and exactly two substituents selected of the group consisting of T, V, W, X and Y represent the binding sites connecting of a single bond linking the first chemical moiety to one of the two second chemical moieties.
