| Abstract: An easy prepared fluorescence and UV-Vis dual channel probe for copper ion based on rhodamine-B, which exhibit high sensitivity(2.78×10-8 mol·L-1) and selectivity over other metal ions in mixed aqueous system (H2O∶CH3CN=1∶1，V/V), was developed and characterized. This probe involving rhodamine-B and triphenylamine together through the hydrazine bridge, could coordinate with Cu2+ and result in turn-on response in UV-Vis absorption and fluorescence. Furthermore, the cell stain experiments showed that compound 1 might be used for monitoring Cu2+ within biological samples. | |
