Detecting Hg2+ Ions with an ICT Fluorescent Sensor Molecule:  Remarkable Emission Spectra Shift and Unique Selectivity

Detecting Hg2+ Ions with an ICT Fluorescent Sensor Molecule:  Remarkable Emission Spectra Shift and Unique Selectivity

A fluorescent ratiometric Hg2+ ion sensor RMS, based on a coumarin platform coupled with a tetraamide receptor, is presented. This sensor, employing the ICT mechanism, could be used to specifically detect Hg2+ ions in a neutral buffered water solution with an ∼100-nm blue shift in emission spectra....
