Abstract

This work presents a method for producing new hybrid supramolecular organic-inorganic systems based on tetrapyrrole compounds (natural and artificially synthesized porphyrins) and hexamolibdenonicelate anion to create highly ordered supramolecular complexes based on porphyrins with the possibility of using them in medicine. In particular, the reaction of natural porphyrin (hemin) and the ZnII-complex of tetra(4-pyridyl)porphyrin with the heteropoly compound sodium hexamolibdenonicelate crystalline hydrate Na4[Ni(OH)6Mo6O18]·8H2O in an aqueous medium is considered. This heteropoly compound due to its physicochemical and biological properties can be considered as a part of photochromic materials and pharmacological agent. The optical absorption spectra of the obtained hybrid supramolecular organic-inorganic systems were investigated with the help of electronic absorption spectroscopy. Both the transformation of the bands which are the characteristics of porphyrins and the appearance of new bands indicating the formation of hybrid supramolecular organic-inorganic complexes are observed in the electron absorption spectra. The work traces the role of structural features of porphyrins in the process of their interaction with the heteropolyanions. Differences in the spectral behavior of the two metalloporphyrins when interacting them with the heteropoly compound have been shown and explained by variability in their structure. The data obtained will be useful when developing new hybrid materials as antibacterial components for medical use.
