Patent ID: 7825249

Claim:
An organometallic cryptate of the formula (1) containing at least one metal M coordinated to a cryptand K of the formula (2) where V is a bridging unit, identically or differently on each occurrence, containing 1 to 80 atoms which covalently bonds the three part-ligands L, which may be identical or different on each occurrence, to one another; the three part-ligands L are described by the formula (3) where DCy is a substituted or unsubstituted cyclic group which contains at least one donor atom in the ring or exocyclically bonded, via which atom the cyclic group DCy is bonded to the metal, and CCy is a substituted or unsubstituted cyclic group which contains at least one carbon atom, via which the cyclic group CCy is bonded to the metal; the groups DCy and CCy are bonded to one another via a covalent bond and may additionally be linked to one another via substituents and thus define a polycyclic, aliphatic or aromatic ring system.
