Mixed Ferrocene-Cobaltocenium Dendrimers: The Most Stable Organometallic Redox Systems Combined in a Dendritic Molecule

Abstract

Novel peripherally heterogeneous dendrimers in which both ferrocene and cobaltocenium units are attached to the surface of poly(propylene imine) dendritic frameworks (see picture) were prepared. The presence of the two redox-active moieties allows the heterometallic dendrimers to be used as novel types of mediator in amperometric biosensors.
