Abstract
Two approaches to controlled synthesis of the organoinorganic materials obtained by one and twostage surface modification of nanosized silica particles by ptertbutyl thiacalix4arene derivatives have been developed and compared The possibility of the synthesis of the mono or lowdisperse hybrid organoinorganic particles with hydrodynamic diameter varying in the range of 2392–1371 nm depending on stereoisomer and reaction mixture dilution was shown via surface modification of the silica particles The direct acylation of aminated silica leads to covalent macrocyclesilica hybrid clusters of micron size The grafting reaction was confirmed by IR UVspectroscopies dynamic light scattering and thermal analysis
