摘 要: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(λmax)的影响,实验结果表明:标题配合物的Q带λmax在680nm左右;与相同中心金属无取代酞菁金属配合物(669~671nm)比较,标题配合物的Q带λmax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λmax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λmax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λmax影响不明显。UV-Vis absorption spectras of six series (18 kinds) of tetra- azo-aromaticoxy substituted metallophthaloeyanines (R4PcM, R= 4-pyridyloxy, 8-quinolinoxy, 2-methyl-8-quinolinoxy; substitution position, α position and β position; M= Ni ( Ⅱ ), Cu( Ⅱ ), Zn( Ⅱ )) were measured. The effeets of central mentals, the kinds and the positions of substitution groups, and solvents on the metallophthaloeyanines' λmax in Q-band were diseussed. Experimental data show: The λmax in Q-band of title complexes is about 680 nm. In contrast with substitution free metallophthalocyanines(669-671 nm), the λmax 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 λmax in Q-band of the title complexes is more obvious in a position than in β position, and with the same substitution group and central metal, λmax in Q-band of a position substituted complexes exhibits more obvious red-shift than β position substituted complexes. The effects of central metal and solvent on λmax in Q-band of the title complexes aren't obvious.
