Selective and sensitive detection of mercuric ion by novel dansyl-appended calix[4] arene molecules, via fluorescence quenching

摘要

In particular, Compounds of Formula I or Formula II, generally known as calix[4]arenes, may be prepared. The compounds may be used to test samples for the presence of Hg2+ by fluorescence quenching. The compounds may also be used to selectively detect Hg2+ in samples containing other mono- or divalent metals.
