Figure 14. (A) The synthetic route towards MOGs and a schematic illustration of ratiometric fluorescence detection for Hg2+ are presented; (B) Fluorescence emission spectra show the response of MOGs when exposed to various concentrations of Hg2+ under 290 nm excitation; (C) FT-IR spectra demonstrate the characteristics of MOGs both without and with the presence of Hg2+; (D) Competitive interfering experiments[98].
