| Abstract: | A new 3,4-disubstituted-1,8-naphthalimide derivative H1 was designed and synthesized as a selective fluorescent probe for Cu2+ over miscellaneous metal ions in aqueous media. Upon mixing with Cu2+ in CH3OH:H2O (1:1, volume ratio), the increase of fluorescence intensity and a bathochromic shift of absorbance of H1 could be observed with a notable color response (changing from yellow to pink). Furthermore, Cu2+ coordinates to the probe H1 and a 1:1 metal-ligand complex was formed. |
