Fluorometric detection of Hg2+ via metal displacement of BODIPY-Fe(III) complex in aqueous media
A selective and sensitive fluorogenic chemosensor based on Fe3+-BODIPY complex (BPH-Fe) was developed for the specific binding toward Hg2+ in aqueous system. This sensor reveals rapid recognition and simple detection of Hg2+ via metal displacement approach. The BPH-Fe complex showed excellently selective chelation to Hg2+ and was not affected by other interfering metal ions. This developed sensor exhibited the quenching of green fluorescence emission along with yellow to orange color change upon exposure to Hg2+ ion. The stoichiometric ratio of BPH-Fe complex to Hg2+ was established to be 1:1 by Job’s method. The detection limit of the sensor in the determination of Hg2+ was calculated as 1.8 ppb, which is lower than WHO and U.S. EPA allowable level (2 ppb). The X-ray absorption spectroscopy (XAS) probed at Hg L3-edge and Fe K-edge revealed the metal displacement of Fe3+ in BPH-Fe complex to form BPH-Hg2+ complex upon sensing process. Furthermore, BPH-Fe had been successfully employed to determine Hg2+ in living cancer cells.
期刊介绍：
JPPA publishes the results of fundamental studies on all aspects of chemical phenomena induced by interactions between light and molecules/matter of all kinds.
All systems capable of being described at the molecular or integrated multimolecular level are appropriate for the journal. This includes all molecular chemical species as well as biomolecular, supramolecular, polymer and other macromolecular systems, as well as solid state photochemistry. In addition, the journal publishes studies of semiconductor and other photoactive organic and inorganic materials, photocatalysis (organic, inorganic, supramolecular and superconductor).
The scope includes condensed and gas phase photochemistry, as well as synchrotron radiation chemistry. A broad range of processes and techniques in photochemistry are covered such as light induced energy, electron and proton transfer; nonlinear photochemical behavior; mechanistic investigation of photochemical reactions and identification of the products of photochemical reactions; quantum yield determinations and measurements of rate constants for primary and secondary photochemical processes; steady-state and time-resolved emission, ultrafast spectroscopic methods, single molecule spectroscopy, time resolved X-ray diffraction, luminescence microscopy, and scattering spectroscopy applied to photochemistry. Papers in emerging and applied areas such as luminescent sensors, electroluminescence, solar energy conversion, atmospheric photochemistry, environmental remediation, and related photocatalytic chemistry are also welcome.
