A new thiacalixarene diamide (TCAm) has been prepared and its electrochemical property and complexation behavior toward various metal ions have been investigated by voltammetry. p-tert-Butylthiacalixarene diamide (TCAm) exhibited selectivity toward Sr2+ ion over alkali, alkaline earth and transition metal ions while conventional calixarene diamides showed selective binding property with Ca2+ ion. This is probably due to the bigger size of thiacalixarene than those of calixarene.
