Abstract UV-Vis absorption spectras of six series (18 kinds) of tetra- azo-aromaticoxy substituted metallophthalocyanines (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 effects of central mentals,the kinds and the positions of substitution groups, and solvents on the metallophthalocyanines’ λmax in Q-band were discussed. 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 α position than in β position, and with the same substitution group and central metal, λmax in Q-band of α 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.
