A series of starburst amorphous molecules derived from 1,3,5-tris(1-naphthyl)benzene are synthesized by a palladium-catalyzed Miyaura borylation and palladium-catalyzed Suzuki coupling reactions. These starburst compounds have the abilities to form uniform amorphous thin films and possess glass transition temperatures as high up to 254 °C. The high current density and luminance of organic light emitting diodes fabricated indicate that these compounds own good electron-transporting properties. These compounds hence have the potential to be used as electron-transporting materials in organic semiconducting devices.
