Abstract: An uncharged compound of the formula (1) M(L)n(L?)m(L?)o??Formula (1) containing a substructure M(L)n of the formula (3) or (4) M is a transition metal; E is identical or different on each occurrence and is in each case a sp2-hybridized carbon or nitrogen atom; Z is identical or different on each occurrence and is in each case C(R)2 or NR; Cy1 and Cy2 are identical or different on each occurrence and are in each case a substituted or unsubstituted heterocycle which coordinates to M via the N atom and may have a bond to the group Z. The compound can also be used in an oligomer, polymer, dendrimer or an electronic component.

Abstract: The present invention pertains to metal complexes for organic electroluminescent devices and to the devices containing these complexes.

Abstract: Transition metal complexes with quino[7,8-h]quinolines and cyclopentadieno[1,2-h:4,3-h?]diquinolines as proton sponge ligands and a process for their preparation. These complexes are suitable as catalysts, e.g. the palladium complexes for a Heck reaction, as well as for amination and C—H activation reactions. The platinum and palladium complexes are potentially good cytostatic agents.
