摘要: We report the fabrication of a novel easily available turn-on fluorescent water-soluble polymeric chemosensor for Hg2+ ions that was simply prepared by micellar free radical polymerization water-insoluble organic rhodamine-based Hg2+-recognizing monomer (GR6GH), with hydrophilic monomers acrylamide (AM) and acrylic acid (AA). The chemical structure sensor characterized FT-IR 1H NMR spectroscopy. apparent viscosity average molecular weight Mη poly(acrylamide–acrylic acid) [poly(AM–NaAA)] poly(AM–NaAA–GR6GH) were 1.76 × 106 6.84 104 g/mol, respectively. Because its amphiphilic property, can be used as in aqueous media. Upon addition to an solution poly(AM–NaAA–GR6GH), fluorescence enhancements observed instantly. Moreover, other metal did not induce obvious changes spectra. This approach may provide measurable inherently sensitive method ion detection environmental biological applications.
