1. A compound of the formula (1), where the following applies to the symbols and indices used: Ar1 is, identically or differently on each occurrence, a group of the following formula (2), where the structure of the formula (2) can be linked at any desired positions to Ar2 and Ar3 or to N or to further groups Ar1 for n>1; Y is N if the group of the formula (2) is linked via this N to Ar2 or Ar3 or N or Ar1 for n>1 or is, identically or differently on each occurrence, NR, O, S, CR═CR, CR2—CR2 or a group of the following formula (3), where the dashed bonds denote the linking of the group;or Y may furthermore also stand for CR2 if two adjacent groups X together stand for a group of the formula (4), (5) or (6); X is C if the group of the formula (2) is linked via this X to Ar2 or Ar3 or N or Ar1 for n>1 or is, identically or differently on each occurrence, CR or N; or two adjacent groups X together stand for a group of the following formula (4), (5) or (6), where the dashed bonds denote the linking of the group; Z is C if the group of the formula (4) or formula (5) or formula (6) is linked via this X to Ar2 or Ar3 or N or Ar1 for n>1 or is on each occurrence, identically or differently, CR or N; Y1 is on each occurrence, identically or differently, CR2, NR, O or S; Ar2, Ar3 is on each occurrence, identically or differently, an aryl or heteroaryl group having 5 to 18 aromatic ring atoms, which may be substituted by one or more radicals R; Ar4 to Ar7 are selected, identically or differently on each occurrence, from the group consisting of phenyl, ortho-, meta- or para-biphenyl, ortho-, meta- or para-terphenyl, linear or branched quaterphenyl, fluorenyl, spirobifluorenyl and carbazolyl, each of which may be substituted by one or more radicals R; R is on each occurrence, identically or differently, H, D, F, Cl, Br, I, N(R1)2, CN, NO2, Si(R1)3, B(OR1)2, C(═O)R1, P(═O)(R1)2, S(═O)R1, S(═O)2R1, OSO2R1, a straight-chain alkyl, alkoxy or thioalkoxy group having 1 to 40 C atoms or an alkenyl or alkynyl group having 2 to 40 C atoms or a branched or cyclic alkyl, alkoxy or thioalkoxy group having 3 to 40 C atoms, each of which may be substituted by one or more radicals R1, where one or more non-adjacent CH2 groups may be replaced by R1C═CR1, C≡C, Si(R1)2, C═O, C═S, C═NR1, P(═O)(R1), SO, SO2, NR1, O, S or CONR1 and where one or more H atoms may be replaced by D, F, Cl, Br, I or CN, or an aromatic or heteroaromatic ring system having 5 to 60 aromatic ring atoms, which may in each case be substituted by one or more radicals R1, or an aryloxy or heteroaryloxy group having 5 to 60 aromatic ring atoms, which may be substituted by one or more radicals R1, or an aralkyl or heteroaralkyl group having 5 to 60 aromatic ring atoms, which may be substituted by one or more radicals R1, or a diarylamino group, diheteroarylamino group or arylheteroarylamino group having 10 to 40 aromatic ring atoms, which may be substituted by one or more radicals R1; two or more radicals R here may also form a mono- or polycyclic, aliphatic, aromatic and/or benzo-fused ring system with one another; R1 is on each occurrence, identically or differently, H, D, F or an aliphatic, aromatic and/or heteroaromatic hydrocarbon radical having 1 to 20 C atoms, in which, in addition, one or more H atoms may be replaced by F; two or more substituents R1 here may also form a mono- or polycyclic, aliphatic or aromatic ring system with one another; n is 1, 2, 3 or 4; m is 1, 2 or 3; q, r is, identically or differently on each occurrence, 0, 1, 2 or 3; wherein at least two of the groups Ar4 to Ar7 are each substituted by a group of the following formula (7):
-L-(Ar8)p-Q formula (7) in which: L is, identically or differently on each occurrence, a spacer group or a direct bond; Ar8 is, identically or differently on each occurrence, an aromatic or heteroaromatic ring system having 5 to 24 aromatic ring atoms, which may be substituted by one or more radicals R; Q is, identically or differently on each occurrence, a crosslinkable group; p is, identically or differently on each occurrence, 0 or 1. |
