Self-assembled monolayers with oligo-ethyleneoxy linkages on flat and curved gold surfaces
摘要:
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 tetrathiafulvalenyl-alkane monothiol and the ether-substituted alkane monothiol adsorbed 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-tetrathiol and the ether-substituted tetrathiol adsorbed onto gold electrodes. The reaction of a thiol bearing oligo-ethyleneoxy linkages with octanethiolate-stabilized gold clusters gave the new oxy-Au clusters containing ether linkages which were dissolved in nonpolar and polar solvents.

Coordination complexes of tetrathiafulvalene-based dithiolene linkers, such as tetrathiafulvalene-2,3,6,7-tetrathiolate (TTFtt), and their oxidation products are described. The coordination complexes can include metals such as tin or silicon. Also described are methods of using the coordination complexes in transmetallation reactions, e.g., to prepare sulfur coordination polymers, and sulfur coordination polymers doped with tetrathiafulvalene-based dithiolene linkers having different oxidation states.

Gold electrodes, on which multilayered metal–TTF derivatives (M–TTFS4) were assembled, exhibit a redox activity, and the redox potentials are sensitive to the metal ions being coordinated. The M–TTFS4 showed broad and very strong absorbance in the range of near IR, attributed to the charge-transfer band between the metal ions and the ligand.
