Abstract

Double-ended alkanedithiols, 1,9-nonanedithiol and 1,5-pentanedithiol. formed self-assembled monolayers (SAMs) on Au(111) substrates and were used toadsorb silver ions from an ethanolic solution of silver nitrate and formedAg-dithiol-Au multilayer structures. Ellipsometry, contact angle measurement and X-ray phototelectron spectroscopy (XPS) confirmed that the alkenedithiol molecules formed SAMs with only one-ended thiol groups attached to theAu substrates, which was supported by molecular mechanics calculation. XPSand X-ray Auger electron spectroscopy (XAES) indicated that silver ions were deposited onto the SAMs from the solution by the chemical reaction of silver nitrate with another-ended thiol groups of the SAMs. Atomic force microscopy (AFM) was used to observe SAMs and multilayer structures.
