The first observation of four-electron reduction in [60]fullerene-metal cluster self-assembled monolayers (SAMs)†
Abstract
Self-assembled monolayers (SAMs) of a μ3-η2∶η2∶η2-C60 triosmium cluster complex Os3(CO)8(CN(CH2)3Si(OEt)3)(μ3-η2∶η2∶η2-C60) (2) on ITO or Au surface exhibit ideal, well-defined electrochemical responses and remarkable electrochemical stability being reducible up to tetraanionic species in their cyclic voltammograms.
