1. An electronic device comprising at least one compound of formula (II):wherein
R2 is selected from the group consisting of Ar and N(Ar)2;
Ar is on each occurrence, identically or differently, an aromatic or heteroaromatic ring system having 5 to 40 aromatic ring atoms, which are optionally substituted by one or more radicals R13, where, in the case where two Ar are bonded to the same N or P atom, the two Ar may be linked to one another by a single covalent bond or a divalent group selected from the group consisting of BR13, C(R13)2, Si(R13)2, C═O, C═NR13, C═C(R13)2, O, S, S═O, SO2, NR13, PR13 and P(═O)R13;with the proviso that Ar, if it is bonded directly to the aromatic skeleton of the formula (II), is different from triarylamine;R1 and R12 are H;R13 is identical or different on each occurrence and is selected from the group consisting of H, D, F, Cl, Br, I, CHO, N(R14)2, CN, NO2, Si(R14)3, B(OR14)2, OSO2R14, straight-chain alkyl, alkenyl, alkoxy and thioalkoxy groups having 1 to 40 C atoms and branched, monocyclic or polycyclic alkyl, alkenyl, alkoxy and thioalkoxy groups having 3 to 40 C atoms, each of which are optionally substituted by one or more radicals R14, where one or more non-adjacent CH2 groups are optionally replaced by R14C═CR14, C≡C, Si(R14)2, Ge(R14)2, Sn(R14)2, C═O, C═S, C═Se, C═NR14, P(═O)(R14), SO, SO2, NR14, O, S or CONR14 and where one or more H atoms are optionally replaced by D, F, Cl, Br, I, CN or NO2, and aromatic or heteroaromatic ring systems having 5 to 40 aromatic ring atoms, which in each case are optionally substituted by one or more radicals R14, and aryloxy or heteroaryloxy groups having 5 to 40 aromatic ring atoms which are optionally substituted by one or more radicals R14, and a combination of these systems, where two or more adjacent substituents R13 optionally define a monocyclic or polycyclic, aliphatic or aromatic ring system with one another;R14 is identical or different on each occurrence and is selected from the group consisting of H and an aliphatic hydrocarbon radical having 1 to 20 carbon atoms, where one or more H atoms of the aliphatic hydrocarbon radical are optionally replaced by F; where, in the case where two or more substituents R14 are adjacent, these optionally define a monocyclic or polycyclic aliphatic ring system;
with the proviso that the following compounds are excluded: |
