Self-assembled monolayers of a tetrathiafulvalene-based redox-switchable ligand

Abstract

A straightforward synthesis of new thiol derivatives incorporating the tetrathiafulvalene (TTF) moiety is presented. These electroactive systems form highly stable self-assembled monolayers (SAMs) on gold electrodes. The electrode obtained by SAM formation from a thiol derivative whose structure associates the redox-active TTF unit and a crown-ether ligating part, allows the voltammetric recognition of barium.
