Rhodamine triazole-based fluorescent probe for the detection of Pt(2+).
A rhodamine triazole-based fluorescent chemosensor has been developed for the selective detection of platinum ions in aqueous solutions. The rhodamine 6G hydroxamate linked with a propargyl group is converted to the corresponding triazole by a "click" reaction. The dual binding unit composed of a hydroxamate and a triazole shows high selectivity and sensitivity toward Pt(2+) over a range of other metal ions in water. The fluorescent probe is applied to monitor cisplatin in aqueous solutions.
