BRANCHED polyphenylene - poly (1,3,5-triphenylbenzene-4'-triyl) centered BRANCHING - 1.3,5-TRIFENILBENZOLNOE core has the properties of electroluminescence HIGH PERFORMANCE AND METHOD OF PRODUCING

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to new polymer compounds, which can be used as active layers of organic light-emitting diodes with high radiation efficiency in the blue range. New branched polyphenylenes are proposed with general formula (I): , where n - ranges from 10 to 20; R - C₁-C₁₀alkyl, C₁-C₁₀alkoxy group, with high electroluminescence efficiency. A method is also described for producing polyphenylenes of formula (I), which involves homopolycondensation of 1,3,5-tri(n-bromophenyl)benzene in the presence of catalyst, formed in situ based on nickel chloride, triphenylphosphine, bipyridyl and zinc, in an argon current with subsequent reaction of the reaction product with C₁-C₁₀alkyl or C₁-C₁₀ alkoxyphenylbromide.;EFFECT: modified polyphenylenes have good optical characteristics compared with known modified polyphenylenes.;3 cl, 4 dwg, 1 tbl, 6 ex
