The present invention relates to novel compounds according to formula (I) having a six-membered ring structure substituted with electron donor, electron acceptor and sterically demanding groups. Said compound is suited for use in organic electronic devices, particularly in organic electroluminescent devices (OLEDs). Formula (I) wherein Q1 and Q2 are independently of each other selected from the group consisting of N, CRA, CRD, and CRS; Z1 and Z2 are independently of each other selected from the group consisting of N, CRA and CRD; RA is a group with -M-effect; RD is a group with +M-effect; and RS is a sterically demanding group, with the provision that the compound of general formula (I) comprises at least one group CRA and at least one group CRD. |
