Abstract: | Methods of synthesis of a number of new functionalized phthalocyanines, as well as MgII, CoII, CuII, ZnII, and NiII phthalocyaninates, that involve benzo-15-crown-5-, phosphoryl-, or pyridine-containing fragments as peripheral substituents, which were developed and tested in IPCE RAS in the last five years, are reviewed and systematized. Methods of synthesis of the original phthalogens, which involve substituents of diverse composition, are considered. Results of an investigation of the aggregate states of the compounds in water and aqueous solutions of salts are generalized. The possibilities of electrostatic immobilization of the synthesized phthalocyanines in the form of self-assembled systems composed of ultrathin ionic layers on quartz and conductive glasses are considered. Based on the spectral, electrochemical, and electrocatalytic properties, the role of noncovalent interactions in the synthesis and operation of the composite systems is clarified. |
