A simple fluorescent receptor selective for Mg2

A structurally simple fluorescent receptor (receptor 1) has been synthesized and was found to show a dramatic enhancement in its fluorescence emission upon complexation with Mg(2+). This was maybe contributed to by the inhibition of the C=N isomerization in the excited state. The experimental result...

Summary:A structurally simple fluorescent receptor (receptor 1) has been synthesized and was found to show a dramatic enhancement in its fluorescence emission upon complexation with Mg(2+). This was maybe contributed to by the inhibition of the C=N isomerization in the excited state. The experimental results show that the receptor was selective and sensitive towards Mg(2+) in the presence of competing ions, with a low detection limit of 3.5 × 10(-9) mol L(-1) (3σ).
