A Fluorescence Sensor for Cu2+ and Co2+ Based on Click-Generated Triazole Moiety
Abstract. The novel tetraphenylethylene (TPE) based sensor 1 bearing bis(2-pyridin-2-ylmethyl) amine (BPA) unit and BODIPY unit linked with triazole moieties could be obtained by click reaction efficiently. It was employed as a fluorescence probe for the selective recognition of Cu2+ and Co2+. They form stable 1:1 stoichiometric complexes and the lowest limit of detection was 1×10-7 M.
