Abstract: Branched oligoarylsilanes of general formula (I) XmQk-SiArn—R)3]2??(I). A method of preparation of branched oligoarylsilanes is that a compound of general formula (III) Y-Qk-SiArn—R)3??(III), where Y stands for a residue of boronic acid or its ester or Br or I, reacts under Suzuki conditions with a reagent of general formula (IV) A-Xm-A??(IV), where A stands for: Br or I, provided that Y stands for a residue of boronic acid or its ester; or a residue of boronic acid or its ester, provided that Y stands for Br or I. A technical result is preparation of novel compounds, featured by a high luminescence efficiency, efficient intramolecular energy transfer from some molecular fragments to others, and an increased thermal stability.
