Abstract
The present invention relates to new types of metal complexes. Such compounds can be used as active components (=functional materials) in a series of different types of applications which can be classed within the electronics industry in the widest sense. The inventive compounds are described by the structure 1 and the formulae (1) to (60).
Claims30
Compounds of the structure 1,
- containing at least one metal Met coordinated to a polypodal ligand Lig of the structure 2,
- where V is a bridging unit, characterized in that it contains from 1 to 80 atoms and the three part-ligands L1, L2 and L3 which may be the same or different at each instance are covalently bonded to one another, and where the three part-ligands L1, L2 and L3 satisfy the structure 3
- where Cy1 and Cy2 are the same or different at each instance and correspond to substituted or unsubstituted, saturated, unsaturated or aromatic homo- or heterocycles or part-homo- or part-heterocycles of a fused system, which are each bonded ionically, covalently or coordinatively to the metal via a ring atom or via an atom bonded exocyclically to the homo- or heterocycle, and that the compounds of the structure 1 are uncharged.
Compounds as claimed in characterized in that the polypodal ligand Lig of the structure 5 generates meridional coordination geometry on the metal Met
