几种锌酞菁衍生物的光谱性质研究

On The Spectral Properties of Several Zinc Phthalocyanine Derivatives

合成了无取代锌酞菁(1)、四硝基锌酞菁(2)、四氨基锌酞菁(3)、丁二酸酐改性的锌酞菁(4)和顺丁烯二酸酐改性的锌酞菁(5),研究了这些酞菁衍生物的红外光谱、紫外可见光谱和荧光光谱.结果表明,在DMSO溶液中,所有酞菁配合物在2-16×10-6 mol/L浓度范围内均遵循朗伯-比尔定律;在水溶液(pH约为13)中酞菁4和酞菁5在2-16×10-6 mol/L浓度范围内也遵循朗伯-比尔定律.在DMSO中,除酞菁2外,其它酞菁的吸收光谱和激发光谱相似,且与发射光谱呈镜像关系.

The non-substituted phthalocyanine zinc（1）,tetranitro-phthalocyanine zinc（2）,tetraamino-phthalocyanine zinc（3）,zinc phthalocyanine with succinic anhydride（4） or maleic anhydride（5） tetrasubstituted have been synthesized.The synthesized phthalocyanine complexes have been characterized by FT-IR,UV-vis and fluorescence spectra.The results show that all the phthalocyanine complexes obey Lambert-Beer Law in the concentrations ranging from 2×10-6 to 16×10-6 mol/L in DMSO.Phthalocyanines 4 and 5 also obey Lambert-Beer Law in the concentrations ranging from 2×10-6 to 16×10-6 mol/L in aqueous solution.In fluorescence spectra,all studied zinc phthalocyanine complexes except phthalocyanine 2 show that the excitation spectra are similar to absorption spectra and both are mirror images of the emission spectra in DMSO.
