Tetrathiafulvalene-based podands bearing one or two thiol functions : Immobilization as self-assembled monolayers or polymer films, and recognition properties.

Abstract : The synthesis of various thiol and dithiol derivatives of a tetrathiafulvalene-based receptor is presented, as well as their immobilization on gold as self-assembled monolayers (SAMs). The formation of films incorporating TTF units is also shown by electrooxidation of TTF-dithiol derivatives. The ability of the monolayers to electrochemically recognize Pb2+ is demonstrated
