NANO-SIZED AGGREGATES BASED ON DERIVATIVES OF STEREOISOMERS OF P-TERTBUTYLTHIACALIX[4]ARENE AND SILVER CATIONS Russian patent published in 2010 - IPC C07D341/00 B82B1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to chemistry and nanotechnology, specifically to aggregates consisting of complexes of silver cations with derivatives stereoisomers of 5,11,17,23-tetra-tert-butyl-25,26,27,28-tetrakis-[(benzylamidocarbonyl)-methoxy]- 2,8,14,20-tetrathiacalix[4]arene, 5,11,17,23-tetra-tert-butyl-25,26,27,28- tetrakis[(benzylamidocarbonyl)-methoxy]-2,8,14,20-tetra-thiacalix[4]arene, 5,11,17,23- tetra-tert-butyl-25,26,27,28-tetrakis[(octylamidocarbonyl)-methox]-2,8,14,20- tetrathiacalix[4]arene, 5,11,17,23-tetra-tert-butyl-25,26,27_,28- tetrakis[(dodecylamidocarbonyl)-methox]-2,8,14,20-tetrathiacalix[4]arene, 5,11,17,23-tetra-tert-butyl-25,26,27,28-tetrakis[(octadecylamidocarbonyl)-methoxy]-2,8,14,20-tetrathiacalix[4]arene, which are nano-sized - with diametre of 84-154 nm, are formed and exist in solution (in non-polar organic solvents), and the structure and size of aggregates depend on the type of alkyl substitute in the calixarene molecule and configuration of the macrocycle.

EFFECT: production of nano-sized aggregates with given diametre based on complexes of substituted thiacalix[4]arenas with silver cations, which can be used for making materials containing nano-sized aggregates and having antibacterial properties, as well as for making catalysts, for extracting silver cations from industrial wastes, for making medicinal agents in pharmaceutics.
