NOVELTY - Metal complex (I) is new.    USE - (I) is useful in a conjugated, partly conjugated or non-conjugated oligomers, polymers or dendrimers; and organic electronic components. The ligand is useful for preparing (I) (all claimed).    DETAILED DESCRIPTION - Metal complex (I) of formula (M(L)n(L-a)m(L-b)o) is new.    M(L)n = ligand complex of formula (II);    M = iridium, platinum, palladium, gold, tungsten, rhenium, ruthenium or osmium;    D1 = heteroatom (which is sp2-hybridized with a non-bonding electron pairs that coordinates at M);    C = sp2-hybridized C-atom (which binds at M);    E = sp2 hybridized C or N atom;    Y1 = CR2, C (=O), C(=NR), C(=N-NR2), C(=CR2), SiR2, O, S, S(=O), S(=O)2, Se, NR, PR, P(=O)R, AsR, As(=O)R or BR;    Cy1 = substituted homo or heterocyclic atom (that over a sp2-hybridized C atom binds at M);    Cy2 = substituted heterocyclic (which coordinates over D1 at M);    either R = H, F, CN or 1-40C (preferably 3-40C) (cyclic)alkyl or alkoxy (where one or more non-adjacent CH2 group of R2C=CR2, C=C, Si(R2)2, Ge(R2)2, Sn(R2)2, O, S, NR2, (C=O), (C=NR2), P=O(R2) or CONR2 is replaced and H-atoms is replaced by F), (hetero)aromatic, 1-30C (hetero)aryloxy group (which is replaced by R1); or    2R = aliphatic or aromatic ring system;    either R1 = H, F, Cl, Br, I, OH, NO2, CN, N(R2)2, 1-40C (preferably 3-40C) alkoxy (one or more non-adjacent CH2 group of R2C=CR2, C=C, Si(R2)2, Ge(R2)2, Sn(R2)2, O, S, NR2, (C=O), (C=NR2), P=O(R2) or CONR2 is replaced and H-atoms is replaced by F), (hetero)aromatic, 1-30C (hetero)aryloxy (which is replaced by one or more non-aromatic R1); or    2R1 = mono-, polycyclic-, aliphatic or aromatic ring);    R2 = H or 1-20C aliphatic or aromatic hydrocarbon;    L-a, L-b = monoanionic or bidentate chelating ligand;    n = 1-3; and    m, o = 0-2.    INDEPENDENT CLAIMS are included for:    (1) the preparation of (I);    (2) a conjugated, partly conjugated or non-conjugated oligomers, polymers or dendrimers comprising (I) (where R and R1 are bonded to polymers or dendrimers); and    (3) a organic electronic component comprising (I), oligomers, polymers or dendrimers.
