| Abstract | The determination of mercuric ions (Hg2+)in environmentaland biological samples has attracted the attention of researcherslately. In the present work, a novel turn-on Hg2+ fluorescentprobe utilizing a rhodamine derivative had been constructed and prepared.The probe could highly sensitively and selectively sense Hg2+. In the presence of excessive Hg2+, the probe displayedabout 52-fold fluorescence enhancement in 50% H2O/CH3CH2OH (pH, 7.24). In the meantime, the colorlesssolution of the probe turned pink upon adding Hg2+. Uponadding mercuric ions, the probe interacted with Hg2+ andformed a 1:1 coordination complex, which had been the basis for recognizingHg2+. The probe displayed reversible dual colorimetricand fluorescence sensing of Hg2+ because rhodamine’sspirolactam ring opened upon adding Hg2+. The analyticalperformances of the probe for sensing Hg2+ were also studied.When the Hg2+ concentration was altered in the range of8.0 × 10–8 to 1.0 × 10–5 mol L–1, the fluorescence intensity showed anexcellent linear correlation with Hg2+ concentration. Adetection limit of 3.0 × 10–8 mol L–1 had been achieved. Moreover, Hg2+ in the water environmentand A549 cells could be successfully sensed by the proposed probe. |
