Mixed diphthalocyanines of rare earths containing sterically hindered substituents and their redox properties

Method for obtained new monophtalocyanines of the rare earth elements, containing voluminous substitutes, bound by amide groupings with macroring, in one stage through direct temple synthesis from acid chlorides, 4-aminophthalonitrile and salts of rare earth elements is proposed. Capability to reversible single electron oxidation-reduction transformations is shown by means of absorption spectroscopy for the series of Nd, Eu and Zn diphthalocyanines, separated as green forms
