Abstract: A metal-organic coordination compound, which is neutrally charged and wherein the coordination compound comprises at least one divalent lanthanide coordinated by a cyclic organic ligand, wherein the cyclic organic ligand contains two monoanionic groups covalently linked with the cyclic organic ligand and being separated from each other by a sequence of at least two intervening atoms.

Abstract: A metal-organic coordination compound, wherein the coordination compound comprises at least one divalent lanthanide coordinated by a cyclic organic ligand according to formula 1:






wherein

i is larger than 3; and
n is equal to 1, 2, or 3; and
L for each occurrence is independently selected from

divalent cyclic organic groups that can be substituted and that are formed by removing two hydrogen atoms from an organic cyclic molecule that can be substituted,
arylenes, preferably 5- or 6-membered ring aromatic or heteroaromatic group, or
biradical fragments of












and



X is independently selected for each occurrence from the group of:










wherein R1 and R2 are hydrogen or any covalently bound substituents being identical or different in each occurrence; and
wherein R1 and/or R2 are at least in 3 occurrences not hydrogen, and
wherein two groups R2 can be covalently linked with each other, thereby forming a further cyclic element,
it also being possible that two cyclic organic ligands of formula 1 are covalently linked with each other by one or two divalent linking groups which divalent linking groups are formed of one R1 of each of the two cyclic organic ligands of formula 1 that are covalently linked with each other.

Abstract: A mixture contains (a) at least one charge neutral metal-organic coordination compound, comprising a divalent Europium coordinated by a polycyclic organic ligand having the formula (1-1) with Y, L0, L1, L2 having a given meaning, (b) at least one second organic compound, which is a charge-neutral host material, wherein the second charge-neutral organic compound has a higher electron binding energy than the charge-neutral metal-organic coordination compound.
