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

Influence of the crystallographic orientation on the reductive desorption of self-assembled monolayers on gold electrodes

“…For alkanethiols, the stability in organic solvents is usually lower than in water [70]. More recent results have shown that the reductive desorption behaviour of SAMs in ionic liquids is markedly different than in aqueous solutions [71]. -Upon desorption of the surfactant, the electrode surface is in contact with the solvent.…”

Formation and modification of a binary self-assembled monolayer on a nano-structured gold electrode and its structural characterization by electrochemical impedance spectroscopy

“…This result demonstrates that selective desorption of MPA from the binary SAMs was successfully performed by applying a negative voltage of À1.2 V, which is a substantial potential for complete desorption of MPA. It also shows that the stability of longer chain thiols (TDT) is higher than that of shorter ones since the highly organized structure could be developed by van der Waals forces between alkyl chains [26,28,29].…”

“…Formation of a binary SAM on a single crystal or polycrystalline planar gold substrate followed by selective desorption has been investigated [27][28][29][30]. Also there have been reports about formation of mono SAMs on the AuNP-modified electrodes [2,3], but very few demonstrated how the selective desorption was effected by the surface modification with gold nanoparticles.…”

Properties of thiolate monolayers formed on different amalgam electrodes

“…Gold [1][2][3], silver [4][5][6], platinum [7,8], copper [6,[9][10][11][12] and mercury [13][14][15][16][17] are the usual materials for the SAM formation. But also some other materials have been applied as substrates for various SAMs: palladium [18][19][20][21], nickel [22,23], iron (mild steel) [24], aluminum [25], zinc [26], indium phosphide [27], indium tin oxide [28], gallium arsenide [29], Ti-Ba-Ca-Cu-O-based high temperature semiconductors [30] and glassy carbon [31,32].…”
