dc.description.abstract | A new ionophore having two pyrenylacetamide moieties based on the p-tert-butylcalix[4]arene-diaza-crown ether has been prepared and its fluoroionophoric properties were investigated. Bis(pyrenyl) derivative was found to exhibit selective ON-OFF type sensing behaviour toward Hg2+ ions over other representative transition and heavy metal ions. The fluorescence quenching efficiency of larger than 20-fold was observed with 100equiv of Hg2+ ions and the association constant was found to be 4.5 x 10(4) M-1 in methanol. The ionophore also exhibited a very efficient quenching of excimer fluorescence selectively upon treatment with Hg2+ ions in 50% aqueous methanol solution. The observed Hg2+ -selective ON-OFF type fluorescence behaviour could be utilized as efficient sensing and switching devices for the design of other supramolecular systems. (C) 2004 Elsevier Ltd.
