摘要
Provided herein are compounds, methods of making the compounds and methods for the sensitive and selective detection of Hg2+ with the compounds, which are calix[4]arenes. In particular, compounds of Formula I, wherein the variables have the values described herein, may be added to a sample to be tested for Hg2+. The compound of; Formula (I) fluoresces strongly in the absence of Hg2+ but is quenched upon binding of Hg2+ to form a complex. The decrease in fluorescence may be used to detect and quantify the amount of Hg2+ present in a sample. The disclosed compounds may also be used to selectively detect Hg2+ in samples containing other mono- or divalent metals.
