A Vibrational Spectroscopic Study of the Structure of Electroactive Self-Assembled Monolayers of Viologen Derivatives

Electrochemical desorption of a self-assembled monolayer of alkanethiol in ionic liquids

“…Computational simulation of linear sweep voltammograms was carried out using a program that was composed by Visual Basic 6.0 based on a formula considering the stabilizing energies due to thiol-thiol and thiol-solvent interactions [24,[45][46][47][48][49][50][51][52][53][54][55]. Each voltammogram shows a cathodic wave indicating reductive desorption of the alkanethiols, and its peak potential is negatively shifted and its width becomes narrow with an increase in chain length.…”

Potential dependent structure transitions of heptyl viologen layers on Cu(100) studied by in situ STM and IRRAS

“…Such redox-active monolayers can, for instance, be formed by viologens, which are among the most intensively studied molecular building-blocks in supramolecular chemistry [1]. Their solution electrochemistry is well documented in literature [8][9][10] and the surface chemistry has been investigated over the past years by electrochemical methods such as Cyclic Voltammetry [11][12][13], STM [14][15][16][17][18][19] and spectroscopic methods like Raman spectroscopy [20][21][22][23][24][25][26] and UV/IR reflectance spectroscopy [27][28][29][30][31][32]. However, only a few reports combine microscopic and spectroscopic methods [33,34].…”

Formation of Ultrathin Films at the Solid–Liquid Interface Studied byIn SituEllipsometry

“…However, only a few methods allow a direct investigation of film formation at the substrate-solution interface. Correspondingly, few in situ studies of these systems have been reported to date, using atomic force microscopy (2, 3), internal reflection spectroscopy (4,5), or a quartz crystal microbalance (6,7).…”
