Claim 13:
14. The compound as claimed claim 1, wherein the compound is defined by the formulae (I), (II), (IIIa), (IIIb), (IIIc), (IVa), (IVb), (IVc) and (V), where the R radical has the definition given in claim 1 and in addition:
l is an integer in the range from 1 to 8;
m is an integer in the range from 0 to 7;
m+l is not more than 8;
n is an integer in the range from 0 to 6;
o is an integer in the range from 0, 1, 2 or 3;
Ra is the same or different at each instance and is OH, F, Cl, Br, I, CN, NO2, N(Ar)2, N(R1)2, C(═O)N(Ar)2, C(═O)N(R1)2, Si(Ar)3, Si(R1)3, B(Ar)2, B(R1)2, C(═O)Ar, C(═O)R1, P(═O)(Ar)2, P(═O)(R1)2, P(Ar)2, P(R1)2, S(═O)Ar, S(═O)R1, S(═O)2Ar, S(═O)2R1, OSO2Ar, OSO2R1, a straight-chain alkyl, alkoxy or thioalkoxy group having 1 to 20 carbon atoms or an alkenyl or alkynyl group having 2 to 40 carbon atoms or a branched or cyclic alkyl, alkoxy or thioalkoxy group having 3 to 40 carbon atoms, where the alkyl, alkoxy, thioalkoxy, alkenyl or alkynyl group may in each case be substituted by one or more R1 radicals, where one or more nonadjacent CH2 groups may be replaced by R1C═CR1, C≡C, Si(R1)2, Ge(R1)2, Sn(R1)2, C═O, C═S, C═Se, C═NR1, —C(═O)O—, —C(═O)NR1—, NR1, P(═O)(R1), —O—, —S—, SO or SO2, or an aromatic or heteroaromatic ring system which has 5 to 60 aromatic ring atoms and may be substituted in each case by one or more R1 radicals, or an aryloxy or heteroaryloxy group which has 5 to 60 aromatic ring atoms and may be substituted by one or more R1 radicals; at the same time, Ra radicals together with an R radical may also form a ring system.
