tailieunhanh - Synthesis, characterization, and fluorescence study of phthalhydrazidylazo derivative of an unsaturated diketone and its metal complexes

The Ni(II) and Zn(II) chelates are diamagnetic while Cu(II) complex showed normal paramagnetic moment. The fluorescence maxima of the compound in different solvents show that the emission wavelength increases with increases in the polarity of the solvent. The fluorescence intensity in the presence of Cu(II) ion shows a gradual decrease with increases in the concentration of metal ion. |
