BRANCHED POLYPHENYLENES - POLY-(1,3,5-TRIPHENYLBENZENE-4'-TRIYL) WITH BRANCHING CENTRE - 1,3,5-TRIPHENYLBENZENE RING, WITH HIGH ELECTROLUMINESCENCE EFFECTIVENESS, AND METHOD OF PRODUCING SAID POLYPHENYLENES Russian patent published in 2009 - IPC C08G61/10 C09K11/06

Abstract RU 2370501 C2

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.
