【 摘 要 】

The water-soluble polymeric chemosensor poly(AM-GRBD) has been synthesized by precipitation copolymerization with the functional monomer, GRBD, which was made of N$"$-(rhodamine B-yl) diethylenetriamineand glycidyl methacrylate (GMA) and a hydrophilic co-monomer acrylamide (AM). The chemical sensor behaved as a fluorescent and chromogenic sensor towards various heavy metal cations and transition metal cations; particularly,Cr$^{3+}$, Fe$^{3+}$ and Hg$^{2+}$ ions in completely aqueous media. The fluorescence of poly(AM-GRBD) was enhanced by Cr$^{3+}, Fe$^{3+}$ and Hg$^{2+}$ metal ions. Moreover, during titration of Cr$^{3+}$, Hg$^{2+}$ or Fe$^{3+}$ to the aqueous solution of poly(AM-GRBD), the visual colour changed from colourless to pink or brown yellow under visible light.
