1. An electronic device comprising an anode, a cathode and at least one compound of the formula (1) containing a metal M coordinated to a ligand L of the formula (2) where the following applies to the symbols and indices used:M is selected from Cu(I), Ag(I), Au(I), Ni(0), or Pd(0);a is 0 and V is N or P, and V is coordinated to M through an electron lone pair, ora is 1 and V is not coordinated to M, and is selected from B, BR−, CR, CO−, SiR, NR+, or P(═O); or V is a cyclic group of one of the formulae (31) to (34)Y is, identically or differently on each occurrence, a divalent group selected from CR2, BR, SiR2, NR, PR, P(═O)R, O or S;b is 1;L1 is selected from the groups of the formulae (3) to (30):X is on each occurrence, identically or differently, CR or N;D is on each occurrence, identically or differently, O−, S−, NR−, PR−, NR2, PR2, COO−, SO3−, —C(═O)R, —CR(═NR) or —N(═CR2);
and the groups are coordinated to the metal M via the position denoted by *; the position denoted by # indicates the position at which the part-ligand is bonded to Y or to V, and the position denoted by (#) indicates the position at which the part-ligand is optionally bonded to Y or to L4, and if a further bond of this type to Y or to L4 is present, the corresponding symbol X(#) is C, and there is no group R bonded to the symbol N(#) in the formulae (7), (8), (9), (21) and (23);L2 and L3 are selected, identically or differently on each occurrence, from the group consisting of —NR2, —NR−, —N═C(R1)2, —PR2, —PR(OR), P(OR)2, —S−, —SR and L1;L4 is a carbon monoxide, nitrogen monoxide, alkyl cyanide, aryl cyanide, alkyl isocyanide, aryl isocyanide, amine, halophosphine, trialkylphosphine, triarylphosphine, alkylarylphosphine, phosphite, arsine, stibene, neutral or anionic nitrogen-containing heterocycles, carbene, hydride, deuteride, F−, Cl−, Br−, alkylacetylide, arylacetylide, cyanide, cyanate, isocyanate, thiocyanate, isothiocyanate, aliphatic or aromatic alcoholate, aliphatic or aromatic thioalcoholates, amide, carboxylate, orwherein, in formula (56), X and D are as defined for formulae (3) to (30), * indicates the position of the coordination to M, and the position denoted by (#) indicates the position at which L4 is optionally bonded, optionally via —(Y)n—, one of the part-ligands L1, L2 and L3 and if L4 is bonded to the part-ligand L1, L2 or L3 directly or through Yn, the corresponding symbol X(#) is C;n is on each occurrence, identically or differently, 0, 1 or 2;R is on each occurrence, identically or differently, H, D, F, Cl, Br, I, N(R1)2, CN, NO2, OH, Si(R1)3, B(OR1)2, C(═O)R1, P(═O)(R1)2, S(═O)R′, S(═O)2R1, OSO2R1, a straight-chain alkyl, alkoxy or thioalkoxy group having 1 to 40 C atoms or a branched or cyclic alkyl, alkoxy or thioalkoxy group having 3 to 40 C atoms or an alkenyl or alkynyl group having 2 to 40 C atoms, each of which is optionally substituted by one or more radicals R1, where one or more non-adjacent CH2 groups is optionally replaced by R1C═CR1, C≡C, Si(R1)2, Ge(R1)2, Sn(R1)2, C═O, C═S, C═Se, C═NR1, P(═O)(R1), SO, SO2, NR1, O, S or CONR1 and where one or more H atoms is optionally replaced by F, Cl, Br, I, CN or NO2, 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, heteroaryloxy, aralkyl or heteroaryalkyl 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 is optionally substituted by one or more radicals R1; two or more substituents R here may also form a mono- or polycyclic, aliphatic, aromatic, heteroaromatic and/or benzo-fused ring system with one another;R1 is on each occurrence, identically or differently, H, D, F, Cl, Br, I, N(R2)2, CN, NO2, OH, Si(R2)3, B(OR2)2, C(═O)R2, P(═O)(R2)2, S(═O)R2, S(═O)2R2, OSO2R2, a straight-chain alkyl, alkoxy or thioalkoxy group having 1 to 40 C atoms or a branched or cyclic alkyl, alkoxy or thioalkoxy group having 3 to 40 C atoms or an alkenyl or alkynyl group having 2 to 40 C atoms, each of which may be substituted by one or more radicals R2, where one or more non-adjacent CH2 groups is optionally replaced by R2C═CR2, C≡C, Si(R2)2, Ge(R2)2, Sn(R2)2, C═O, C═S, C═Se, C═NR2, P(═O)(R2), SO, SO2, NR2, O, S or CONR2 and where one or more H atoms is optionally replaced by F, Cl, Br, I, CN or NO2, 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 R2, or an aryloxy, heteroaryloxy, aralkyl or heteroaryalkyl group having 5 to 60 aromatic ring atoms, which is optionally substituted by one or more radicals R2, or a diarylamino group, diheteroarylamino group or arylheteroarylamino group having 10 to 40 aromatic ring atoms, which is optionally substituted by one or more radicals R2; two or more substituents R1 here may also form a mono- or polycyclic, aliphatic, aromatic, heteroaromatic and/or benzo-fused ring system with one another;R2 is on each occurrence, identically or differently, H, D, F, or an aliphatic, aromatic or heteroaromatic radical having 1 to 20 C atoms, in which, in addition, one or more H atoms is optionally replaced by F; two or more substituents R2 here may also form a mono- or polycyclic, aliphatic, aromatic, heteroaromatic and/or benzo-fused ring system with one another. |
