Laboratory of calixarene chemistry

The Laboratory was established in 2000.

Corresponding Member of RAS Igor S. Antipin is the
head of the Laboratory since its foundation.

Main research activity

  • The development of methods for stereo- and chemoselective modification of (thia)calix[4]arene platform including the application of click-chemistry approaches. A series of extractants, based on lipophilic stereoisomers of tetrasubstituted by the lower rim (thia)calix[4]arenes derivatives, capable of effectively and selectively extract the high-dangerous radionuclide Tc (VII) was synthesized.
  • Synthesis of nanosized molecules with receptor and (or) amphiphilic properties. The first examples of a new class of nanosized macrocyclic compounds – conjugates of (thia)calix[4]arenes and clathrochelates – are obtained. Calixresorcinarene macrocycles forming a continuous phase of thermoreversible gel in neutral aqueous solutions at low concentrations were designed. One molecule of the gelator immobilizes up to 10000 water molecules.
  • Construction of supramolecular systems and machines.Supramolecular system based on host-guest complexes of water-soluble calix[4]resorcinarene in which photo induced electron transfer controlled by the pH of the medium was elaborated.
  • Design of metal-organic structures (MOF"s). The unique metal-organic framework (MOF"s) formed by decanuclear clusters of silver ions was obtained by supramolecular self-assembly method.
