PHYSICOCHEMICAL PROPERTIES OF NOVEL MIXED-LIGAND COMPLEXES OF ZIRCONIUM AND HAFNIUM BIS(4-BENZOYL-3-METHYL-1-PHENYL-2-PYRAZOLIN-5-ONATO)PHTHALOCYANINATES

摘要

We have studied the spectral(IR,PMR,electronic absorption spectra)and luminescent properties of novel mixed-ligand complexes of zirconium(IV)and hafnium(IV)phthalocyaninates with 4-benzoyl-3-methyl-l-phenyl-2-pyrazolin-5-one in different organic solvents.We have determined the fluorescence quantum yields,the natural lifetimes of the excited states,and the molar extinction coefficients for the complexes.
