摘要: 利用UV-Vis吸收光谱、荧光光谱及半经验ZINDO/S方法,研究了4种可溶性镍酞菁(FPcNi、MePcNi、iBPcNi、iPPcNi)的电子吸收光谱和荧光光谱.研究结果表明:随着取代基的供电子能力增加,酞菁的最大吸收波长(λmax)和发射波长(λem)发生红移,摩尔消光系数变小;随着溶液浓度增大,酞菁聚集体浓度增大,λmax发生蓝移,但浓度对λem影响较小,同时荧光相对强度随浓度增大,出现最大值;随着溶剂配合能力的增加,λmax、λem都发生红移.

关键词: 镍酞菁, 吸收光谱, 荧光光谱, ZINDO/S

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
