摘要/Abstract

摘要： 设计合成了4’-(二茂铁基)-2,2’:6’,2″-三联吡啶钴(Ⅱ)配合物1以及参比配合物4’-(4-甲苯基)-2,2’:6’,2″-三联吡啶钴(Ⅱ)配合物2和2,2’:6’,2″-三联吡啶钴(Ⅱ)配合物3,配合物1中二茂铁基给电子基团的引入使其在可见光区的吸收明显增强,并在部分氧化时呈现混合价态的电荷转移(MVCT)吸收.

关键词: 三联吡啶钴(Ⅱ)配合物, 二茂铁, 混合价态电荷转移

Abstract: Cobalt(Ⅱ)-bis[4’-ferrocenyl-2,2’:6’,2″-terpyridyl] complex 1 and reference complexes cobalt(Ⅱ)-bis[4’-(4-methylphenyl)-2,2’:6’,2″-terpyridyl](2) and cobalt(Ⅱ)-bis[2,2’:6’,2″-terpyridyl](3) were designed and synthesized.Complex 1 exhibits obvious low-energy absorption from 500 to 700 nm due to introduction of electro-donating ferrocenyl group,which could be switched to mixed-valence charge transfer state ranged from 500 to 800 nm upon partial oxidation.

Key words: Cobalt(Ⅱ) terpyridyl complexes, ferrocenyl, mixed-valence charge transfer
