英文摘要	Electrochemical measurements, in situ scanning tunneling microscopy (STM) observation, and molecular mechanics (MM) simulations were performed to study the physiochemical properties such as the corrosion-inhibition effect and the optimal packing structure of o-aminothiophenol (OATP) self-assembled monolayer (SAM) formed on Fe(110) surface in 0.1 M NaClO4 solution. The formation of OATP SAMs drastically depressed the Faradaic processes at the Fe(110) surface and reduced the electrical double-layer capacitance at the electrode/electrolyte interface, revealing the anticorrosion property and the blocking behavior of OATP adlayers. Two-dimensional ordered molecular arrays of OATP on Fe(110) surface with a p(2 x 2) commensurate structure were observed by STM measurements. MM calculations showed that the p(2 x 2) packing pattern is indeed the preferable structure for OATP molecules adsorbed on Fe(110), in accordance with STM experiments. The OATP SAM on Fe(110) is 0.50 nm in thickness and with a dielectric constant of similar to7.0. (C) 2004 Elsevier B.V. All rights reserved.
