摘要: A new family of a-cinnamoyl cyclic ketene dithioacetals (CCKDA) based on a typical donor-pi-acceptor structure were designed and synthesized. These unsymmetrical pi-conjugated molecules consisted of different electron-donating moiety and the same ketene dithioacetals acceptor. The introduction of different donor moieties changed energy level parameters of the molecules and allowed a fine tuning of their optical and electrical properties. It is promising to apply these compounds in organic light-emitting diodes (OLED) as light-emitting and electron-transporting materials.
