摘要:

通过二碘代二茂铁与不同炔化物进行Sonogashira偶联反应,合成了3种新颖的含有二茂铁单元的苯乙炔齐聚物,用1H NMR、13C NMR和MS测试技术分别对其结构进行了表征。 并借助量子化学计算对3种分子的电子结构进行了预测,结果显示,该类型分子导线具有不同于其它类型苯乙炔齐聚物的LUMO能级持续衰减特征,因此极有可能具备极为优良的电子传输性能。

Abstract:

Three novel ferrocene-based oligo(phenylene ethynylene)s molecular wires were prepared by the Sonogashira coupling reaction of 1,1′-diiodoferrocene with different acetylenic compounds. The structures of all the products were confirmed by 1H NMR, 13C NMR and MS. The electronic structures of these molecular wires were forecasted by a quantum chemistry calculation, which indicated that they might contain favorable charge transport properties due to their abnormal LUMO energy level continuous attenuation.

Key words: ferrocene, oligo(phenylene ethynylene)s, molecular wires
