The introduction of metal chemosensors on polymeric system was attempted with azide-alkyne click reaction. This reaction yields triazole group as a binding site, which cooperates with proximal ligands for metal complexation. Clean and simple removal of the catalyst after coupling reaction was issued and successfully resolved with polymer supports. The polymer sensor was prepared by the click reaction of rhodamine based chemosensors on acrylic copolymer. The binding contribution of a triazole group improves selectivity of the rhodamine sensors, depending on metals such as Cu, Hg, Al ion, etc. Three different polymers such as anionic, cationic, and zwitterionic polymers were examined for the better water-soluble property. The sensing performance of the prepared polymers is discussed in micro to nano molar concentration of metal ions.
