In Final Form: December 5, 1994@ w-Alkoxy-n-alkanethiols (HS (CH2)" OR) adsorb from solution onto the surfaces of evaporated silver and gold films and form oriented self- assembled monolayers (SAMs). For many of these SAMs (R 2 propyl), the wetting properties of the SAMs by various polar and nonpolar liquids are indistinguishable from those of SAMs derived from n-alkanethiols and suggest that the presence of the ether oxygen atom is not ...
