title: Detecting Hg2+ ions with an ICT fluorescent sensor molecule: remarkable emission spectra shift and unique selectivity.
abstract: 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 approximately 100-nm blue shift in emission spectra.
