Anion selectivities of membranes based on cationic complexes of thioamide calix[4]arene derivatives are presented for the first time. Hg II complexes of thioamide derivatives of calix[4]arene were applied to design perchlorate‐selective ISEs which show linear responses in the range 1–5 of pClO 4 with a slope of 56.5mV decade −1 . The highest selectivity over other anions (except iodides) and optimum performances of electrodes were obtained for a 0.01 M solution of Hg II as an internal electrolyte.
