Structural and electrochemical characterization of fullerene-based surfaces of C_(60) mono- or bis-adducts grafted onto self-assembled monolayers

摘要

Single layers of C_(60) mono- and bis-adducts have been obtained by functionalizing an acid-terminated self-assembled monolayer (SAM) of thiols on gold. X-ray photoelectron spectroscopy demonstrated the grafting onto the SAM by covalent bonding, via the formation of an amide bond, while cyclic voltammetry and electrochemical impedance spectroscopy provided information on the redox properties of the C_(60)-films, as well as on structural characteristics.
