ABSTRACT:
The fluorescence properties of novel transition metal Cu(II), Ni(II), Co(II) and Zn(II) complexes of bidentate Schiff base ligand {8-[(E)-{[3-(dimethylamino)propyl]imino}methyl]-7-hydroxy-4- methyl-2H-chromen-2-one]} [DMAPI MHMC] obtained from 4-Methyl-7-hydroxy 8-formylcoumarin, and dimethylamino propane-1,3-diamine have been prepared and characterized by physical, spectral and analytical data. The Schiff base act as 1,5-bidentate ligand for the complexation reaction with Cu(II), Ni(II), Co(II) and Zn(II) halides. The new compounds, possessing the general formula [ML2.2H2O] where [M= Cu(II), Ni(II), Co(II) and Zn(II)] show octahedral geometry. It is further subjected to fluorescence study. The Schiff base shows strong emmision at 503, 507, 508, 509 513 and 514 nm for the excitaion wavelengths 295, 375, 399, 430, 751, 800 and 847nm but the complexes shows strong emission at 400 nm [ZnL2, at 500 nm], 400 nm [CuL2, at 403 and 465 nm], 401 nm [NiL2, at 404, 445 and 810 nm] and 401 nm [CoL2, at 409, 438, 478, 808 and 854 nm].
