AB  - A dendrimer (termed G2) containing pyrene as the core and 9-phenylcarbazole (PCZ) 
      on the periphery is shown to be a multi-functional fluorescent probe for iodide, 
      iron(III) and mercury(II). It serves as the fluorometric/colorimetric 
      dual-channel probe for these ions. As a fluorometric probe, the fluorescence of 
      G2 is quenched both by iodide and iron(III). After that, the fluorescence of G2 
      which has been added iodide will recover when added mercury(II); as a 
      colorimetric probe, the color of G2 solution can turn to yellow only by iodide 
      which will change from yellow to colorless again when adding mercury(II). The 
      color change is sensitive and observed visually at 0.1 mM for iodide. G2 also is 
      an electroactive precursor for preparation of fluorescent films via 
      electropolymerization. The resulting films can be used as the fluorescent films 
      to sense the ions. This is attributed to the presence of a large specific 
      surface, highly cross-linked microstructures and enhanced pi conjugation. The 
      electropolymerized film has blue fluorescence with excitation/emission maxima at 
      365/460 nm. The limits of detection (LOD) of G2 for iodide, iron(III) and 
      mercury(II) were calculated to be 9.3, 37.1 and 22.0 nM in solution and 5.1, 12.0 
      and 6.1 nM in films, respectively. The linear range is from 2 to 10 muM for G2 
      electropolymerized films. The detection range is from 2 to 400 muM for iron(III) 
      and mercury(II). The detection range is from 2 to 130 muM for iodide. For a third 
      application, G2 displays compelling sensing performance in environmental systems 
      and in living roundworms. Graphical abstractAs schematic presentation, after 
      adding iodide, the fluorescence of G2 is quenched and the color changes to 
      yellow. When adding Hg(2+) to G2-iodide, the fluorescence and color of G2 
      recover. Iron(III) can also quench G2, but the color does not change.
