Abstract:
1. A compound of the formula (1) where the compound of the general formula (1) contains a moiety M(L) where the following applies to the symbols and indices used: M is a metal; Y is on each occurrence, identically or differently, C or N; a double bond may in each case also be present between the two atoms Y or between the adjacent atoms Y and A which are bonded in Cy1, or between the two atoms Y or the adjacent atoms Y and A which are bonded in Cy2; Cy1 is selected from the structures of the following formulae (3) to (26): where E stands, identically or differently on each occurrence, for S, O or NR; where * indicates the position of the coordination to the metal; where # indicates the bond to Cy2 or to X in the ligand L; Z is, identically or differently on each occurrence, C(═O), C(═S), CR Cy2 is on each occurrence, identically or differently, Cy1 or is on each occurrence, identically or differently, an aryl or heteroaryl group together with the group A and the two groups Y, where both groups Y in Cy2 stand for C if Cy2 stands for a six-membered aryl or heteroaryl ring group; Cy2 here optionally is substituted by one or more radicals R; A is on each occurrence, identically or differently, C or N; X is on each occurrence, identically or differently, CR or N; R is on each occurrence, identically or differently, H, D, F, Cl, Br, I, N(R R R L′ is, identically or differently on each occurrence, any desired co-ligand; anion is anion; n is 1, 2 or 3; m is 0, 1, 2, 3 or 4; w is 1, 2 or 3; x, y, z are on each occurrence, identically or differently, 0, 1, 2 or 3, where (w·x)=(y·z); a plurality of ligands L here may also be linked to one another or L optionally is linked to L′ via any desired bridge V and thus form a tridentate, tetradentate, pentadentate or hexadentate ligand system.
