四氮杂芳氧基取代酞菁金属配合物的UV-Vis吸收光谱研究

测定了6个系列18种四氮杂芳氧基取代酞菁金属配合物(R₄PcM, R=4-吡啶氧基、8-喹啉氧基、2-甲基-8-喹啉氧基;取代位置分别为：α位及β位;M=Ni(Ⅱ), Cu(Ⅱ), Zn(Ⅱ))的UV-Vis吸收光谱。探讨了中心金属、取代基种类及取代位置、溶剂对酞菁金属配合物UV-Vis吸收光谱中Q带最大吸收波长(λ_max)的影响，实验结果表明：标题配合物的Q带λ_max在680 nm左右;与相同中心金属无取代酞菁金属配合物(669～671 nm)比较，标题配合物的Q带λ_max都发生了不同程度的红移;当取代基在α位时其种类对标题配合物Q带λ_max的影响较在β位时显著，且相同取代基及中心金属的α位取代配合物的Q带λ_max较β位取代配合物的红移更为明显;中心金属、溶剂对标题配合物的Q带λ_max影响不明显。

Study on UV-Vis Absorption Spectra of Tetra-Azo-Aromaticoxy Substituted Metallophthalocyanines

UV-Vis absorption spectras of six series (18 kinds) of tetra- azo-aromaticoxy substituted metallophthalocyanines (R4 PcM, R = 4-pyridyloxy, 8-quinolinoxy, 2-methyl-8-quinolinoxy; substitution position: a position and beta position; M = Ni (II), Cu(II), Zn(II)) were measured. The effects of central mentals, the kinds and the positions of substitution groups, and solvents on the metallophthalocyanines' lamdamax in Q-band were discussed. Experimental data show: The lamdamax in Q-band of title complexes is about 680 nm. In contrast with substitution-free metallophthalocyanines(669-671 nm), the lamdamax in Q-band of the title complexes with the same central metal exhibits a different red-shift. The effect of substitution group's kinds on lamdamax in Q-band of the title complexes is more obvious in a position than in beta position, and with the same substitution group and central metal, lamdamax in Q-band of alpha position substituted complexes exhibits more obvious red-shift than beta position substituted complexes. The effects of central metal and solvent on lamda,ax in Q-band of the title complexes aren't obvious.
