This study deals with the use of thiolated calixarene (C[4]A) as gold electrode modifier, alone or in combination with insulating undecanthiol (C11SH), which is used to fill the gaps between calixes. Desorption potential of thiolated C[4]A and C11SH are both pH dependent, cathodic desorption peaks can be recorded in basic solutions only. The properties of the modified electrode were investigated using hydroquinone - electrochemically active molecule which fits inside the C[4]A cavity. Obtained data suggest that the electrochemical oxidation/reduction ofhydroquinone does not use C[4]A cavities as size-selective channels.
