A multi-electron transfer ferrocene derivative positive redox moiety with improved solubility and potential

Abstract

Rational molecular structure modification towards high performance redox couples attracts great concern. A ferrocene derivative N-(pyridin-2-ylmethylene)-1-(2-(diphenylphosphino) ferrocenyl) ethanamine (FeCp₂PPh₂RCN) with improved solubility and potential as well as multi-electron transfer behavior is designed and fabricated. Benefitting from the high operating current density and capacity of the battery, FeCp₂PPh₂RCN demonstrates promising prospects as a positive redox moiety.
