Abstract

Some features of the influence of the structure of water-soluble zinc phthalocyanines on their spectral parameters and state in solutions are studied. It is shown that the position of the long-wavelength electronic absorption band only weakly depends on the type of ionogen substituents in the zinc phthalocyanine macrocycle. It is found that the state of the dye in aqueous solution substantially depends on the type of a substituent in the dye macrocycle.
