title: [Study on UV-Vis absorption spectra of tetra-azo-aromaticoxy substituted metallophthalocyanines].
abstract: 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.
