Provided herein are compounds, methods of making the compounds and methods for the sensitive and selective detection of Hg
2+
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 Hg
2+
. The compound of
Formula (I) fluoresces strongly in the absence of Hg
2+
but is quenched upon binding of Hg
2+
to form a complex. The decrease in fluorescence may be used to detect and quantify the amount of Hg
2+
present in a sample. The disclosed compounds may also be used to selectively detect Hg
2+
in samples containing other mono- or divalent metals.
本文提供了一些化合物、制备这些化合物的方法以及使用这些化合物进行对Hg2+的敏感和选择性检测的方法,这些化合物是杯[4]
芳烃。特别地,公式(I)的化合物,其中变量具有所述值,可添加到待测试Hg2+的样品中。化合物在没有Hg2+的情况下强烈发荧光,但在与Hg2+结合形成复合物后被猝灭。荧光的减少可以用于检测和定量样品中存在的Hg2+的量。所披露的化合物也可以用于在含有其他单价或二价
金属的样品中选择性地检测Hg2+。
