Polycrystalline gold electrode modified by thiols
Šustrová, Barbora ; Mareček, Vladimír ; Štulík, K.
The article reports on our continued investigation of modification of the gold electrode surface by thiolated compounds aimed at construction of an ion-selective sensor. Our previous work was focused on utilization of calix[4]arene molecules as a cavity sized ligand molecule. In this paper, calixarene and linear undecanethiol molecules were used as modifiers. We compared two ways of deposition thiol molecules, namely the spontaneous self-assembly process and the electrochemical deposition, in which the potential was applied on the electrode immersed into an adsorption solution. The concentration, time and potential conditions were optimized from the point of view of the SAM homogeneity. The modifying layers of calixarene and undecanthiol molecules were visualized by atomic force microscopy.

A study of calixarene self-assembled monolayers on gold metal surfaces
Šustrová, Barbora ; Mareček, Vladimír ; Štulík, Karel
Substituted calix[4]arene molecules were self-assembled on the gold disk electrode surface and the structure of the monolayer formed and the electrochemical behavior of the modified electrode were studied. The formation of the calixarene self-assembled monolayer (SAM) conformed to a Langmuir-type adsorption isotherm, The atomic force microscopy measurement results indicated that the calixarene molecules form a stable monolayer on the Au(111) surface and confirmed the cyclic voltammetry results concerning the SAM structure dependence on the solvent used. Impedance measurements demonstrate that the capacity of the modified electrode varies in the presence of ions, depending on their size and shape.
