| Abstract: | Two stable blue-light-emitting molecular materials containing twisted binaphthyl and peripheral triphenylamine groups were synthesized by Suzuki and Heck cross-coupling reactions. Both compounds exhibit excellent thermal and morphologic stabilities, high glass transition temperatures and good fluorescence quantum yield in films. They serve as both hole-transporting and blue emission materials in organic light-emitting diodes with good external quantum efficiencies. |
