FIELD: chemistry.
SUBSTANCE: invention relates to field of chemical technology of silicon-organic compounds. Technical task lies in synthesis of novel polyarylsilane links including dendrimers of large generations suitable for application as luminescent materials for organic electronics and photonics. Claimed are dendrimers of general formula (I) 
where R1 stands for substituent from group: linear or branched C1-C20alkyl groups; linear or branched C1-C20alkyl groups separated by at least one oxygen atom; linear or branched C1-C20 alkyl groups separated by at least one sulphur atom; branched C3-C20 alkyl groups separated by at least one silicon atom; C2-C20alkenyl groups; Ar represents, independently for each n and m, similar or different arylene radicals, selected from group: substituted or non-substituted thienyl-2,5-diyl of general formula (II-a) 
substituted or non-substituted phenyl-1,4-diyl of general formula (II-b) 
substituted or non-substituted 1,3-oxazol-2,5-diyl of general formula (II-c) 
substituted fluorene-4,4'-diyl of general formula (II-d) 
where R2, R3, R4, R5, R6 represent independently on each other H or said above for R1; R7 stands for said above for R1; K is equal 2 or 3 or 4; L is equal 1 or 3 or 7 or 15; m and n represent whole numbers from series from 2 to 6. Method of obtaining dendrimers lies in the following: monodendron of general formula (III) 
where X represents H or Br or I, first reacts with lithiumising agent of general formula R8Li, where R8 represents linear or branched C1-C10alkyl group, dialkylamide or phenyl group; then obtained compound reacts with functional compound selected from group of compounds of formula (CH3)4-KSiYK, where Y represents Cl, or Br, or -OCH3, or -OC2H5, or -OC3H7, or -OC4H9. Claimed method is technological, use of expensive catalysts is not required.
EFFECT: elaboration of technological method of synthesising novel polyarylsilane dendrimers which does not require use of expensive catalysts.
