Özet:

 

The coupling of diazotized luminol with the unsaturated diketone  1,7-diphenylhepta-4,6-diene-1,3-dione yielded a new type of tridentate  ligand (H2L). Analytical, IR, 1H NMR, and mass spectral data  indicate the existence of the compound in the intramolecularly  hydrogen-bonded keto-hydrazone tautomeric form. Dibasic tridentate  coordination of the compound in its [ML(H2O)] complexes [M = Cu(II),  Ni(II) and Zn(II)] was established on the basis of analytical and spectral  data. 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.
