| abstract |
The invention relates to an organic molecule having exactly two units according to formula I, which are linked to each other by single bond or by a bridge Y, where Y = a divalent group; X = the same or different CN or CF3 in each occurrence; D = chemical unit having a structure of formula I-1 wherein # = connecting point of the unit according to formula I-1 to the structure according to formula I; A and B = independently of each other selected from the group consisting of CRR1, CR, NR, N, wherein there is a single or double bond between A and B and there is 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-Alkinylene or Arylene group or a combination thereof, -CRR1, -C=CRR1, -C=NR, -NR-, -O-, -SiRR1-, -S-, -S(O)-, -S(O)2-, by O interrupted, substituted or unsubstituted C1-C9-Alkylene, C2-C8-Alkenylene, C2-C8-Alkinylene or arylene group, Phenyl or substituted Phenyl units. |
