The invention relates to an organic molecule having precisely two units of formula I linked to one another via a single bond or a bridge Y
where
Y=a divalent group;
X=at each occurrence identically or differently CN and CF3;
D=chemical unit having a structure of the formula I-1:
where
#=attachment point of the unit of formula I-1 to the structure of formula I;
A and B=independently of one another are selected from the group consisting of CRR1, CR, NR, N, there being a single or double bond between A and B and a single or double bond between B and Z;
Z=a direct bond or a divalent organic bridge which is a substituted or unsubstituted C1-C9-alkylene, C2-C8-alkenylene, C2-C8-alkynylene or arylene group or a combination thereof, —CRR1, —C═CRR1, —C═NR, —NR—, —O—, —SiRR1—, —S—, —S(O)—, —S(O)2—, O-interrupted substituted or unsubstituted C1-C9-alkylene, C2-C8-alkenylene, C2-C8-alkynylene or arylene group, phenyl units or substituted phenyl units.
