Popis:	The peculiarities have been studied of silver organosol formation in the breakdown of Ag(I) complex (synthesized by us) with 2-[4,6-di(tert-butyl)-2,3-dihydroxyphenylsulfanyl]-acetic acid in solvents (dimethyl formamide, methanol, ethanol, propanol-2, butanol-1) of a high donor number (DN = 27–34). The dispersiveness and assembly peculiarities of silver nanoparticles in organosols were examined by means of absorbance spectroscopy, TEM and AFM. The organosol stability essentially depends on the nature of the dispersive medium, and on whether water and/or oxygen are present therein. The Ag(I) complex was shown to be a promising solid precursor in production of silver nanoparticles. Employing this precursor a new method of forming silver nanoparticles in polyelectrolyte capsule walls is proposed.
