DENDRONISED POLYARYLSILANES AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2012 - IPC C08G77/60 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical engineering of organosilicon compounds. Disclosed are novel dendronised polyarylsilanes of general formula

, where R denotes a substitute from: linear C₁-C₁₂ or branched C₃-C₂₀ alkyl groups; linear C₁-C₁₂ or branched C₃-C₂₀ alkyl groups, separated by at least one oxygen atom; linear C₁-C₁₂ or branched C₃-C₂₀ alkyl groups, separated by at least one sulphur atom; branched C₃-C₂₀ alkyl groups, separated by at least one silicon atom; C₂-C₂₀ alkenyl groups; Ar denotes identical or different arylene or heteroarylene radicals selected from: substituted or unsubstituted thienyl-2,5-diiyl; substitured or unsubstituted phenyl-1,4-diiyl, substituted fluorene-4,4'-diiyl. X denotes identical or different arylene or heteroarylene radicals selected from said group for Ar and/or a radical from 2,1,3-benzothiodiazole-4,7-diiyl, anthracene-9,10-diiyl; L equals 0 or a an integer from 1, 3, 7, 15; k is an integer from 1 to 6; m is an integer from 1 to 6; t is an integer from 2 to 10; n is an integer from 5 to 10000. A method of producing said compounds is also disclosed.

EFFECT: synthesis of novel chemical compounds, characterised by high efficiency of luminescence, high molar absorption coefficient and high thermal stability.
