TECHNOLOGY FOCUS - ELECTRONICS - Preferred Components: The organic light diode comprises an anode, a cathode and at least a light emitting layer between the anode and the cathode and optionally at least a further layer consisting of at least a block layer for hole/exciton, at least a block layer for electron/exciton, at least a hole-injection layer, at least a hole conductor layer, at least an electron injection layer and at least a electron conductor layer, where the light emitting layer and/or further layer contains (Q) or crosslinked or polymerized material. The block layer for hole/exciton contains (Q) or the crosslinked or polymerized material. The organic light diode emits white light.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Claimed): Preparation of (Q) comprises contacting a residue or a group (in which R is SiR1R2R3, A and R4 and R5 are obtained by (a) introducing R4, R5, SiR1R2R3 or A of suitable precursor compound, contacting a residue R and contacting R4, R5, SiR1R2R3 and A, or (b) bringing the residue R, introducing R4, R5, SiR1R2R3 and A of suitable precursor compound and contacting R4, R5, SiR1R2R3 and A, or (c) introducing R4, R5, SiR1R2R3 or A of suitable precursor compound, contacting R4, R5, SiR1R2R3 and A, and contacting a residue R, or (d) introducing R4, R5, SiR1R2R3 and A of suitable precursor compound and contacting R4, R5, SiR1R2R3 and A) into dibenzene base structure of formula (II).X = NR, S, O, PR, NH, PH or phenylphosphine.Preferred Process: The halo-metal exchange takes place at halogenated (II) using diethyl ether as a solvent. The silane educt is simultaneously obtained using (II), in which further a metal reagent is added. Preferred Definitions:    A = pyrrolyl, 2,5-dihydro-1-pyrrolyl, pyrrolidinyl, indolyl, indolinyl, isoindolinyl, carbazolyl, azacarbazolyl, diazacarbazolyl, imidazolyl, imidazolinyl, benzimidazolyl, pyrazolyl, indazolyl, 1,2,3-triazolyl, benzotriazolyl, 1,2,4-triazolyl, tetrazolyl, 1,3-oxazolyl, 1,3-thiazolyl, pentazolyl, piperidyl, morpholinyl, 1,4-oxazinyl, 9,10-dihydroacridinyl (all optionally substituted by one or more alkyl, cycloalkyl, heterocycloalkyl, (hetero)aryl or a group with donor- or acceptor effect); and    R1-R25, R28 = polymerizable or crosslinkable group bonded over a spacer, which is functional groups, that are radically, cationally or through polyaddition or coupling reactions polymerizable or crosslinkable, preferably -C=C-, acrylate, methacrylate, oxetanyl or 1,2-epoxyether.    SPECIFIC COMPOUNDS - 116 Compounds (Q) are specifically claimed e.g. (8-(diphenyl-phosphinoyl)-dibenzofuran-2-yl)-triphenyl-silane of formula (Ia), (8-(diphenyl-phosphinoyl)-dibenzothiophen-2-yl)-triphenyl-silane, 9-(8-triphenylsilanyl-dibenzothiophen-2-yl)-9H-carbazole, 9-(8-triphenylsilanyl-dibenzofuran-2-yl)-9H-carbazole and 3,6-dimethyl-9-(8-triphenylsilanyl-dibenzofuran-2-yl)-9H-carbazole.    EXAMPLE - A solution of 9-(3-methoxyphenyl)-3,6-dibromo-9H-carbazole (26 g) in dry tetrahydrofuran (700 ml) was reacted with n-butyl lithium (41 ml) at -78 degrees C under argon and stirred for 2 hours. Further a solution of chlorotriphenylsilane (30 g) in dry tetrahydrofuran (150 ml) was added and heated under stirring. Excess butyl lithium was hydrolyzed with saturated ammonium chloride solution. The precipitated products were filtered and thoroughly washed with methyl chloride. The concentrated methylene chloride-filtrate was extracted with water and dried. The residue was stirred with acetone and filtered to obtain 3-bromo-9-phenyl-6-triphenylsilyl-carbazole (74%).
