A Novel Colorimetric Chemosensor Based on Calix[4]arene Derivative for Mercury Ion
首发时间:2008-09-27
Abstract:A calix[4]arene derivative (2) possessing bis(indolyl) groups has been synthesized in satisfied yield, and further its response to metal ions was investigated by the methods of UV-vis spectrometry. The results obtained show that 2 displays high sensitivity to Hg2+. The addition of Hg2+ made the absorption spectrum of 2 appear a new band around ca 500 nm, and caused obvious color change of solution from colorless to orange-yellow. Hence, the detection of Hg2+ can be easily found by naked eyes. Calixarene 2 may be used for application as Hg2+-selective chemosensor, even in aqueous solution.
