| titleOfInvention | Novel branched oligoarylsilanes and method for producing same |
| abstract | Novel branched oligoaryl silanes and processes for their preparation are claimed. The novel branched oligoaryl silanes of formula (I) , Wherein R is a linear or branched C 1 -C 20 alkyl group which is a series of substituents; A linear or branched C 1 -C 20 alkyl group separated by at least one oxygen atom; A linear or branched C 1 -C 20 alkyl group separated by at least one sulfur atom; The at least one silicon atom separated by a branched C 3 -C 20 alkyl group; A C 2 -C 20 alkenyl group; Ar represents a series of substituted or unsubstituted thienyl-2,5-diyl, substituted or unsubstituted phenyl-1,4-diyl, substituted or unsubstituted 1,3-oxazole-2,5- Substituted or unsubstituted cyclopentadithiophene-2,7-diyl, or a substituted or unsubstituted arylene or heteroarylene radical selected from substituted cyclopentadithiophene-2,7-diyl; Q represents a radical from the series described above for Ar; X is at least one radical selected from the series described above for Ar and / or a series of radicals such as 2,1,3-benzothiadiazole-4,7-diyl, anthracene-9,10- 2-pyrazolene-3,5-diyl, perylene-3,10-diyl, and n represents a series of integers of 2 to 4 ; m represents a series of integers from 1 to 3; k represents an integer of 1 to 3 in the series. The process for the preparation of the branched oligoaryl silanes comprises reacting a compound of formula III Under Suzuki conditions with a reagent of formula IV Wherein Y represents a residue of a boronic acid or an ester thereof or Br or I and A represents Br or I when Y represents a residue of a boronic acid or an ester thereof, Br or I, a residue of a boronic acid or an ester thereof. As a result, novel compounds are produced which are characterized by high luminous efficiency, efficient intramolecular energy transfer from some molecular fragments to the rest of the molecular fragments, and increased thermal stability. |
