TECHNOLOGY FOCUS - POLYMERS - Preparation (Claimed): The preparation of the polymer comprising (I), is carried out by Suzuki polymerization, Yamamoto polymerization, Stille polymerization or Hartwig-Buchwald polymerization. Preferred Components: The polymer in addition to (I), comprises further structural units, which exhibits: hole injection- and/or hole transport properties, comprising triarylamine-, benzidine-, tetraaryl-p-phenylenediamine-, triarylphosphine-, phenothiazine-, phenoxazine-, dihydrophenazine-, thianthrene-, dibenzo-p-dioxin-, phenoxathiin-, carbazole-, azulene-, thiophene-, pyrrole- or furan derivatives or oxygen, sulfur or nitrogen containing heterocycles with high values of highest occupied molecular orbital; electron injection and/or electron transport properties comprising pyridine-, pyrimidine-, pyridazine-, pyrazine-, oxadiazole-, quinoline-, quinoxaline-, anthracene-, benzanthracene-, pyrene-, perylene-, benzimidazole-, triazine-, ketone-, phosphine oxide- or phenazine derivative or triarylborane or further oxygen, sulfur or nitrogen containing heterocycles with low values of lowest unoccupied molecular orbital. The further structural elements alter the emission characteristics of the polymer such that an electrophosphorescence is obtained instead of electrofluorescence. The polymer comprises further structural elements: that improve the transition from singlet- to triplet state, comprising carbazole-, bridged carbazole dimer units, ketones, phosphine oxides, sulfoxides, sulfones and silane derivatives; that influence the emission color of the polymers, comprising 1,4-phenylene-, 1,4-naphthylene-, 1,4- or 9,10-anthrylene-, 1,6-, 2,7- or 4,9-pyrenylene-, 3,9- or 3,10-perylenylene-, 4,4'-biphenylene-, 4,4''-terphenylene-, 4,4'-bi-1,1'- naphthylene-, 4,4'-tolanylene-, 4,4'-stilbenylene-, 4,4''-bis-styrylarylene-, benzothiadiazole- and corresponding oxygen derivatives, quinoxaline-, phenothiazine-, phenoxazine-, dihydrophenazine-, bis(thiophenyl)arylene-, oligo(thiophenylene)-, phenazine-, rubrene-, pentacene- or perylene derivatives; that are typically used as backbone, comprising 4,5-dihydropyrene-, 4,5,9,10-tetrahydropyrene-, fluorene-, 9,9'-spirobifluorene-, phenanthrene-, 9,10-dihydrophenanthrene-, 5,7- dihydrodibenzo-oxepin-, or cis- and trans-indenofluorene derivatives. Preferred Definitions:    Z1-Z3 = Cl, Br, I, O-tosylate, O-triflate, O-SO2R22, B(OR22)2 or Sn(R22)3; either    R22 = H, aliphatic or aromatic 1-20C hydrocarbon; or    at least two R22 = ring.    EXAMPLE - 12,12,22,22-Tetramethyl-N,N-diphenylhexacyclo(11.11.0.0(2,11).0(3,8).0(15,23).0(16,21))tetracosa-1(24),2(11),3,5,7,9,13,15(23),16,18,20-undecaen-9-amine (20g) was dissolved in chloroform (300ml) and tetrabutylammonium tribromide (37.5g) was added to it in portions at room temperature. Then the reaction mixture was stirred at room temperature for 2 hours. Then the reaction mixture was worked up to obtain N,N-bis(4-bromophenyl)-12,12,22,22-tetramethylhexacyclo(11.11.0.0(2,11).0(3,8).0(15,23).0(16,21))tetracosa-1(24),2(11),3,5,7,9,13,15(23),16,18,20-undecaen-9-amine(A). Then (A) (2%) 2,2'-(9,10-dioctylphenanthrene-2,7-diyl)bis(1,3,2-dioxaborolane) (50%) and 2,8-dibromo-6,6-bis-(4-tert-butyl-phenyl)-12,12-dioctyl-6,12-dihydro-indeno(1,2-b)fluorene (48%) were reacted by Suzuki coupling to obtain the polymer.
