Abstract: RhA,a kind of rhodamine B derivative,is designed and synthesized,and its characteristics is detected by means of fluorescence and ultraviolet analysis methods.RhA probe is a chemo-sensor for Cu2+.RhA alone has no color and low fluorescence intensity in a 2×10-5 mol·L-1 HEPES-CH3CN (a volumetric ratio of 1:1,containing 0.1 mol·L-1 of NaNO3,pH=7.4) solution.After adding Cu2+,the solution gradually turns pink,and the fluorescence is significantly enhanced,but there is hardly response to other common metal ions.The fluorescence spectrum show that RhA still shows a good linear relationship for the detection at a lower concentration of Cu2+ at 10 μmol·L-1.This method has potential application value for the rapid and real-time detection of Cu2+ in actual water environment.
