The preparation and properties of the self-assembled monolayers with oligo-
ethyleneoxy linkages on flat and curved gold surfaces have been described.
The electrochemical properties of the self-assembled monolayers of a tetrat
hiafulvalenyl-alkane monothiol and the ether-substituted alkane monothiol a
dsorbed onto gold electrodes showed no difference in their redox potentials
and surface coverages. In contrast, the difference between the alkyl chain
and the oxy-alkyl chain in the redox potentials and surface coverages was
found in the self-assembled monolayers of the tetrathiafulvalenyl-tetrathio
l and the ether-substituted tetrathiol adsorbed onto gold electrodes. The r
eaction of a thiol bearing oligo-ethyleneoxy linkages with octanethiolate-s
tabilized gold clusters gave the new oxy-Au clusters containing ether linka
ges which were dissolved in nonpolar and polar solvents. (C) 2000 Elsevier
