Highly fluorescent blue-emitting materials from the Heck reaction of triphenylvinylsilane with conjugated dibromoaromatics

Article abstract of DOI:10.1055/s-2006-951506

A new family of conjugated, highly photoluminescent 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 °C) make them excellent candidates for active materials in organic light-emitting diodes (OLEDs).
