abstract |
A new fluorescent probe based on Tellurium-Rhodamine (TR) was designed, synthetized and fully characterized by H-1 NMR, C-13 NMR, Te-125 NMR, HRMS, IR and single crystal X-ray diffraction. A mechanism of Hg2+ detection, based on the oxidation of tellurium by Hg2+ was observed and fully understood. The new monomer chemosensor TR shows a high fluorescent quantum yield Phi = 0.41, excellent selectivity and good sensibility towards Hg2+, with a limit of detection of 2.95 mu mol/L. |
