Abstract: The spectral characteristics of soluble nickel phthalocyanines(FPcNi、MePcNi、iBPcNi、iPPcNi) were studied by UV Vis absorption spectroscopy,fluorescence spectroscopy and semi expirical ZINDO/S method.The results show that(1) the electron donating substituents caused slightly red shift with the maximum absorption wavelength(λmax) and emission wavelength(λem),and declined the molar absorption coefficient;(2)increasing the concentration leaded to slightly blue shift of theλmax,and little affected the λem,but the fluorescence intensity had a maximum with the increasing of the concentration;(3)with the strengthening of coordination ability of the solvent,theλmaxandλemhad red shift.

Key words: nickel phthalocyanine, absorption spectra, fluorescence spectra, ZINDO/S
