In this work, a novel pyridylvinyl rhodamine-naphthalimide ratiometric fluorescent probe, In this work, a novel pyridylvinyl rhodamine-naphthalimide ratiometric fluorescent probe, RNVP, was synthesized and characterized by 1H NMR, 13C NMR and HRMS techniques. This probe shows high selectivity and sensitivity towards Fe3+ and Hg2+. At a low concentration of Fe3+/Hg2+, a new emission peak appeared at...
A novel ratiometric fluorescent chemodosimeter REPN based on 1,8-naphthalimide-rhodamine was successfully synthesized. Two different strategies of fluorescence resonance energy transfer (FRET) and photo-induced electron transfer (PET) for ratiometric detection of Hg2+/Fe3+ were designed into one sensing system. REPN exhibits typical FRET signal from pyridine-naphthalimide moiety to rhodamine moiety...
