Abstract

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
