This invention relates to a hat emitting device which comprises at least one layer that contains an organometallic dendrimer having a core comprising a metal cation. The invention also relates to organometallic dendrimers and methods for producing the same.

Metal-containing dendrimers

This invention relates to a light emitting device which comprises at least one layer that contains an organometallic dendrimer having a core comprising a metal cation. The invention also relates to organometallic dendrimers and methods for producing the same.

Organometallic complexes comprising a trivalent lanthanide metal ion complexed with one or more polydentate ligands containing one or more pyrazolyl-derived groups, such as trispyrazolyl borate species, are useful in light emitting materials e.g., in electroluminescent flat panel displays. In the complexes, several classes of which are novel, a coordinate bond is formed between the metal and one of the nitrogen atoms of the pyrazolyl rings.

Organometallic complexes

A monomer which luminesces in the visible region upon excitation is described of the formula: M(L)(CL)in which n+ is the valency of M, (L) represents one or more anionic ligands with a total valency of n such that at least one of the ligands possesses the formula: Ch-X&#x2014;Y wherein Ch represents a chelating group which is a ligand fragment comprising the chelate binding sites and the part of the rest of the ligand with which the binding sites are conjugated, Y represents an olefinic group and X represents a spacer comprising a chain of at least 4 carbon and/or hetero atoms, x is 0, 1, or 2, CL represents a neutral co-ligand and M represents a metal atom of group 2, 12, 13, d-block or f-block with the proviso that if Y is part of a styrene or substituted styrene group then M is a f-block or d-block metal.
