Abstract
A new azophenol type chromogenic ionophore based on the p-tert-butylcalix[4 ]arenediazacrown ether was prepared: the ionophore exhibited a pronouncedly selective chromogenic behaviour toward Hg2+ ions among the surveyed guests of alkali, alkaline earth, transition and heavy metal ions in liquid-liqui d extraction experiments.
