The structure of the copper complex of the 6-((1-butanethiol)oxy)-tris(2-pyridylmethyl)amine ligand (Cu-tmpa-O(CH2)4SH) anchored to a gold surface has been investigated. To enable covalent attachment of the complex to the gold surface, a heteromolecular self-assembled monolayer (SAM) of butanethiol and a thiol-substituted

We report the covalent surface modification of active-fixation pacemaker electrodes with butanethiol or dodecanethiol self-assembled monolayers (SAMs) using a platinum or gold metal-thiolate bond (i.e., changing the chemical identity of the exposed metal electrode from metal to organic) in such
