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.
测定了六个系列(18种)四氮杂芳氧基取代金属酞菁(R4PcM,R = 4-吡啶氧基、8-喹啉氧基、2-甲基-8-喹啉氧基;取代位置:α位和β位;M = Ni(II)、Cu(II)、Zn(II))的紫外可见吸收光谱。讨论了中心金属、取代基的种类和位置以及溶剂对金属酞菁Q带最大吸收波长(λmax)的影响。实验数据表明:标题配合物的Q带λmax约为680 nm。与无取代金属酞菁(669 - 671 nm)相比,具有相同中心金属的标题配合物的Q带λmax呈现出不同程度的红移。取代基种类对标题配合物Q带λmax的影响在α位比在β位更明显,并且在相同取代基和中心金属的情况下,α位取代配合物的Q带λmax比β位取代配合物呈现出更明显的红移。中心金属和溶剂对标题配合物Q带λmax的影响不明显。
