✦ Synopsis

Electroactive self-assembled monolayers (SAMs) with well-defined electrochemical responses were prepared by spontaneous assembly of the inclusion complexes (CD/C8VC,SH) of viologen-attached alkanethiols (C8VC,SH) and a-and 0-cyclodextrin (CD). They were characterized by X-ray photoelectron spectroscopy and cyclic voltammetry. The results demonstrate that the chemisorption process of CD/C,VC,SH on gold substrate occurs through S-Au bonds, and that the redox sites in SAMs of CD/C8VC,SH are in a much more uniform environment than those in SAMS of CgVC,SH.
