摘要：

A new family of conjugated, highly photo luminescent blue-emitting organosilicon materials prepared from the Heck reaction of triphenylvinylsilane with various dibromoaromatics is described. The products are prepared in one high-yielding step (60-79%) from readily available starting materials. Their high photoluminescent quantum yields (67-98%) coupled with moderate glass transition temperatures (Tg, 69-138 degrees C) make them excellent candidates for active materials in organic light-emitting diodes (OLEDs).
