THE SYNTHESIS OF SILVER NANOPARTICLES BY DECOMPOSITION OF A SILVER COMPLEX WITH THE EFFECT OF VALENCE TAUTOMERISM AND THEIR PROPERTIES

We studied the peculiarities of the formation of silver nanoparticles (Ag NPs) under the intramolecular redox reaction of the Ag(I) complex with 4,6-di-tert-butyl-2,3-dihydroxybenzaldehyde isonicotinoyl hydrazone in organic solvents with high donor numbers (DN > 19). The stability of organosols was shown to be significantly dependent on the nature of the dispersion medium and on the presence of oxygen and water therein. The physico-chemical and morphological characterization of Ag NPs in organosols was carried out by absorbance spectroscopy, TEM, and AFM methods. The silver sol consisted of well-dispersed spherical nanoparticles with a size of 5-20 nm. A typical plasmon absorption band at 440 nm was observed for the Ag NPs. The Ag valence tautomeric complex was found to be a promising precursor of silver nanoparticles. The research demonstrated a high antimicrobial activity of synthesized Ag NPs in comparison with some standard antibiotics and silver-containing agents (MIC=0.007 µmol/ml).
