A new rhodamine B derivative T1 has been rationally designed and synthesized facilely by the condensation reaction of rhodamine B hydrazide and o-phthaloyl chloride. The recognition properties of the target compound T1 with metal ions had been investigated by the fluorescence spectrophotometry. This probe exhibits several favorable features, including instantaneous and reversible recognition, high sensitivity and selectivity to mercury ions. When the concentration of Hg2+ was in the range of 4×10-8~9×10-8 mol/L, there was a good linearity between the fluorescence intensity and the concentration of Hg2+. The fluorescence imaging experiments of Hg2+ in HepG2 living cells demonstrated their valuable application in biological system.
