TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: (II) contains element of the groups 8-10 (ruthenium, osmium, rhodium, iridium, palladium or platinum).    TECHNOLOGY FOCUS - POLYMERS - Preparation: Preparation of (A) comprises polymerization (e.g. Suzuki polymerization and Yamamoto polymerization) of monomers comprising the spiro-repeating units. Preferred Components: (I) is symmetrically replaced at both spiro-molecular halves. The linkage of (I) takes place over same positions (1.1' or 4.4' positions) at the two spiro-molecule halves. (A) is partly conjugated. (A) does not contain further units, which breaks the conjugation of (A). (A) further comprises a structural element (II). The other units (III) are aromatic, 6-40C carbocyclic (optionally substituted by R), fluorine-derivatives, 2,7-spirobifluorene-derivatives, dihydrophenanthrene-derivatives, cis or trans indenofluorene-derivatives, 1,4-phenylene derivatives, 4,4'-biphenylylene derivatives, 4,4"-terphenylylene derivatives, 2,7 or 3,6 phenanthrene derivatives, dihydropyran and/or tetrahydropyrene derivatives. (II) that affects the morphology and optionally the emission color of the resulting polymers, are 6-40C aromatic group (optionally substituted by R), tolane-, stilben- or bisstyrylarylene derivate. (II), increases the hole injection and/or hole transportation characteristics of (A), is group of aromatic amine, phosphine or electron rich heterocycle. (II), increases the electron injection and/or electron transportation characteristics of (A), is electron deficient aromatic group, heterocycle or triarylborane. (II) contains bound units. (II) can emit light at ambient temperature with high efficiency from the triplet state. (II), improves the transition of singlet-triplet state, carbazole derivative, keto, phosphine oxide, sulfoxide, sulfone or silane units. The amount of (III) is at least 30 mol.%. The amount of electron deficient aromatic group, heterocycle or triarylborane is at least 5 (preferably 5-70) mol.%, which improves the charge transfer characteristics. (A) exhibits statistical, alternating or block-like structures or possess several of these structures alternating and linearly, branches or constructed as dendrite. (D) further comprises a polymer light emitting diode, organic field-effect-transistor, organic integrated circuit, organic thin film transistor, organic solar cell, organic field-quench-device or organic laser diode. Preferred Definitions:    n = 0-3;    X = Cl, Br, I, O-tosylate, O-triflate, O-SO2R1, B(OR1)2 or SN(R1)3; and    m = 0-2.    EXAMPLE - A monomer 4,4'-dibromo-1,1'-dimethoxy-spirobifluorene and 9-(3,4-bis-(2-methyl-butoxy)-phenyl)-2,7-dibromo-9-(2,5-dimethyl-phenyl)-9H-fluorene and/or 2,2'-dibromospirobifluorene under goes Suzuki coupling to give a polymer.
