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.
