METAL COMPLEXES WITH TRIDENTATE LIGANDS FOR OPTOELECTRONIC APPLICATIONS

摘要

The invention relates to metal complexes MLX of the following formula (A) and to the use thereof in optoelectronic components, in particular OLEDS, wherein M is selected from the group consisting of Cu, Ag, and Au; C(sp2) = sp2-hybridized carbon atom; A = a bridge with more than 1 and less than 6 (with respect to the shortest chain length) identical or different chain links k, where k = C(sp2)R, CR2, C=O, C=S, C=NR, O, N, NR, S, Se; wherein optionally one or more links of k are also part of an aromatic or aliphatic ring system as defined for C(sp2); E is selected from the group consisting of arsenic and phosphor; E' is selected from the group consisting of NR, PR, AsR, O, S, Se, or N as part of an imine system and, in the case of NR and N, optionally as a component of an aromatic or aliphatic ring system which can optionally be annelated with C(sp2) and/or A into a ring system such as quinoline or isoquinoline as defined for C(sp2); E" = either a chemically neutral group selected from the group consisting of C*R (carbene carbon), NR (imine nitrogen), NR2, PR2, AsR2, OR, SR, SeR, optionally as part of a neutral aromatic or heteroaromatic ring system or a single negatively charged group selected from NR, PR, AsR, O, S, Se, optionally as part of a anionic heteroaromatic ring system; and X is selected from the group consisting of Cl, Br, I, CN, OCN, SCN, alkinyl, and N3; where X is only present when E" = a chemically neutral group.
