The aim of work is synthesis and complexation of bis(benzocrown ethers) with imidazole linkers with ions of alkali and alkaline earth metals for use as sensors and macroheterocycles based on bis(benzimidazol-2-methylene)-ether; establishment of regularities in series of composition-structure-luminescence properties of Cr3+ ions in orthoborates of elements of group III MBO3 (M= Sc, In, Lu). Research methods: organic and inorganic synthesis; thin-layer and gas-liquid chromatography; thermodynamic and kinetic calculations, QSPR analysis and molecular design, spectrophotometry, PMR spectroscopy, mass spectrometry. Imidazole bound bis(benzocrown ethers) were obtained. Complex formation of obtained compounds with cations of alkali and alkaline earth metals was studied by method of spectrophotometric titration. Preparative methods for synthesis of new DBIKE derivatives (15, 30, 34-membered) have been developed, which differ in number of donor centers and varied sizes of the cyclic cavity. A number of experimental samples of DBIKE were developed by cyclization of bis-(benzimidazol-2-methylene)-ether with ditosylates of 1,2-, 1,4-bis-(2-hydroxyethoxy)benzene. Interaction of oxides, silicon and germanium with each other and with zinc oxide was studied. The results were confirmed by thermodynamic calculations. An increase in stability of valence state of silicon (IV) in complex oxide Zn2SiO4 compared to SiO2 was established. Cr3+ ion-doped orthoborates with the MBO3 calcite structure (M= Sc, In, Lu) were synthesized by means of solid-phase reactions.  Product Description popup.authors Efryushina Ninel P. Ivanov Yuri E.
