用于有机电子器件中的具有新型六元环结构的化合物
Abstract:
本发明涉及根据式(I)的新型化合物，其具有被电子给体、电子受体和空间要求严格的基团取代的六元环结构。所述化合物适合用于有机电子器件中，特别是用于有机电致发光器件(OLED)中。在式(1)中，Q1和Q2彼此独立地选自N、CRA、CRD和CRS；Z1和Z2彼此独立地选自N、CRA和CRD；RA是具有‑M效应的基团；RD是具有+M效应的基团；和RS是空间要求严格的基团，条件是所述通式(I)的化合物包含至少一个基团CRA和至少一个基团CRD。
Abstract(English):

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.
