BRANCHED OLIGOARYLSILANES WITH REACTIONABLE TERMINAL GROUPS AND METHOD OF OBTAINING THEREOF Russian patent published in 2015 - IPC C08G77/60 C09K11/06 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to branched oligoarylsilanes with reactionable terminal groups and to method of obtaining them. Claimed are branched oligoarylsilanes with reactionable terminal groups of general formula (I), where R is selected from linear or branched C₁-C₂₀ alkyl groups; C₂-C₂₀ alkenyl groups; R₁ stands for vinyl, 3-propen-1-yl, 4-buten-1-yl, 5-penten-1-yl, 6-hexan-1-yl, 8-octen-1-yl or 11-undecen-1-yl; Ar stands for similar or different arylene or heteroarylene radicals, selected from the group: substituted or non-substituted thienyl-2,5-diyl, substituted or non-substituted phenyl-1,4-diyl, substituted or non-substituted 1,3-oxazole-2,5-diyl, Q stands for radical from said group for Ar, X stands for at least one radical, selected from said group for Ar and/or radical from the group:2,1,3-benzothiodiazole-4,7-diyl, anthracene-9,10-diyl, 1,3,4-oxadiazole-2,5-diyl, 1-phenyl-2-pyrazoline-3,5-diyl, perylen-3,10-diyl; n stands for integer number from 2 to 4; m stands for integer number from 1 to 3; k stands for integer number from 1 to 3. Method of obtaining said oligoarylsilanes is also claimed.

EFFECT: possibility to obtain novel compounds characterised by high luminescence efficiency, effective intramolecular transfer of energy from some molecule fragments to other ones and increased thermal stability.
