The present invention relates to an electronic device comprising a compound according to formula 1 A-B (1) and wherein —Ar 1 is a C6-C18 arylene, which can be monocyclic or polycyclic and may be optionally substituted by one or more C 1 -C 10 -alkyl or C 3 -C 10 -cycloalkyl groups, —Ar 2 is a C6-C18 arene skeleton, optionally substituted with electron donating groups R 4 , —B 1 and B 2 are independently selected from B and Ar 2 , —B 3 is independently selected from the same group as B, —R 1 , R 2 , R 3 are independently selected from alkyl, arylalkyl, cycloalkyl, aryl, dialkylamino, - x is selected from 0, 1, 2 and 3, wherein for x>1 each Ar 1 may be different, - y is a non-zero integer up to the overall count of valence sites on the arene skeleton, - z is a integer from zero up to the overall count of valence sites on the arene skeleton minus y; as well as a respective compound according to formula A-B. |
