Coordination Chemistry of Alkali and Rare Metals Laboratory

Aslan Yu. Tsivadze

Head of Laboratory , Dr. of Sciences (Chemistry), Academician of RAS

  • Development of methods for the synthesis and preparation of new derivatives of crown ethers, including azamacrocyclic (porphyrins, phthalocyanines) and their mononuclear and heteronuclear coordination compounds containing N, O, P-ligand environment, research into their physicochemical properties and structure.
  • Extraction separation of metals and their isotopes using crown compounds; research into extraction systems based on crown compounds for the separation of radionuclides and separation of radioactive metals from ballast metals.
  • Study of the supramolecular chemistry of heterotopic receptors based on crown compounds.

Methods for the directed synthesis of a wide range of coordination compounds based on tetrapyrrole ligands being analogues of natural substances that ensure the vital activity of the biological world were developed.

The fundamentals to prepare new functional materials (thin films, polymer composites, and hybrid materials) based on macrocyclic compounds and supramolecular architectures as the basis for next-generation multifunctional devices were developed.

Physical and chemical bases of radioactive waste processing based on macrocyclic extractants and new-generation sorbents were created.
