Preferred Ligands: Preferred polypodal ligands, corresponding to new compounds (II), have a bridge linking 3 identical or different ring systems, each of which has two 6-membered, two 5-membered or one 6-membered and one 5-membered homo- or heterocyclic rings, either linked by a single bond or in the form of a condensed ring system.Preparation: (claimed) Compounds (I) are prepared by reacting the corresponding ligands (II) with metal alcoholates of formula (83), metal ketoketonates of formula (84) or metal halides of formula (85): M(OR1)3 (83) MHal3 (85);Hal = F, Cl, Br, I.    TECHNOLOGY FOCUS - POLYMERS - Preferred Polymers: In the conjugated, partly conjugated or unconjugated polymers or dendrimers containing compound(s)(I), one or more R groups is a bond to the polymer or dendrimer. The polymer is selected from polyfluorenes, poly-spirobifluorenes, poly-para-phenylenes, poly-carbazoles, poly-vinylcarbazoles, polythiophenes and copolymers of these. The polymer is solvent in organic solvents. Full Definitions:    Met = metal(s);    Lig = a polypodal ligand of formula (2);    V = a bridging unit containing 1-80 atoms;    L1, L2, L3 = sub-ligands of structure (3);    Cy1, Cy2 = identical or different (un)substituted, (un)saturated or aromatic homo- or heterocycles, optionally forming part of condensed systems, with an ionic, covalent or coordinate bond between the metal and a ring atom or an exocyclic atom bound to the homo- or heterocycle.    EXAMPLE - Suzuki coupling was carried out with 51.9 g (100 mmole) tris(2-bromo-6-pyridyl)fluoromethane, 108.0 g (450 mmole) 5-fluoro-2-(tetrahydropyran-2-yloxy)-benzeneboronic acid, 57.5 g (990 mmole) potassium fluoride, 1.35 g (6 mmole) palladium(II) acetate and 1.8 ml (8 mmole) tri-tert.-butylphosphine in 1000 ml tetrahydrofuran (THF). After 6 hours under reflux, the reaction mixture was freed from THF and the residue was taken up in 1000 ml methanol and stirred with dilute hydrochloric acid for 3 hours at 50 degrees C. The crystals were filtered, washed, dried and recrystallized from chloroform, giving 533.2 g (89.0 %) tris(6-(5-fluoro-2-hydroxyphenyl)-2-pyridyl)-fluoromethane (IIA) as colorless crystals, which were over 99.0 % pure. A solution of 5.98 g (10 mmole) (IIA) in 200 ml THF was treated with 19.4 ml (240 mmole) pyridine, then a solution of 20 ml 0.5 N aluminum chloride solution in ethanol was dripped into the solution in 30 minutes at room temperature. The mixture was heated under reflux for 3 hours, then cooled to room temperature. The colorless precipitate was filtered, washed, dried and purified by repeated recrystallization from dimethyl sulfoxide, giving 5.59 g (90.3 %) mono(tris(6-(5-fluoro-2-oxyphenyl)-2-pyridyl)fluoromethanato)aluminum(III) (IA) as a pale yellow complex, which was 99.9 % pure (by 1H-NMR). The hydrolysis stability of (A) the polypodal aluminum complex (IA) was compared with that of (B) the structurally analogous but not polypodal variant tris(5-fluoro-2-oxyphenyl)2-pyridylato)aluminum(III). 10 mM solutions of both complexes in dry dimethyl sulfoxide-d6 were prepared under inert gas and characterized by NMR spectroscopy, then treated with 1000 molar amounts of water at room temperature, left for 10 minutes and tested again. (A) was unchanged, whereas (B) decomposed completely. (A) was not decomposed even after heating the hydrolysis mixture at 180 degrees C for 5 hours.
