摘要

The recognition of mercury(II) ions content in the environment and organisms is of great significance for maintaining the health of the organism and preventing diseases induced by mercury(II) ions. Herein a fluorescent probe which includes rhodamine B and acenaphtho[1,2-b]quinoxaline-9-amin has been designed and synthesized for recognizing mercury(II) ions. The structure of RB-AQ was confirmed by 1H NMR, 13C NMR, HR-MS analyses and single X-ray crystallography. The fluorescent probe RB-AQ exhibited an obvious ?turn-on? fluorescence enhancement for mercury(II) ions at 586 nm. RB-AQ showed good recognization capability and selectivity toward mercury(II) ions over other interfering metal ions in solution. Further, the probe has mercury(II) ions imaging capability in cells and zebrafish.
