Identify regularity of formation supramolecular complexes "guest-host" of bis(crown ethers) and p-tert-butylcalix[4]arenes with organic and inorganic salts and factors that affect on stability and selectivity of complexes are formed to identify dependence of "structure-property-functionality". Development of methods for modeling mixtures and nanoparticles based on inorganic compounds, construction of adequate QSAR/QSPR models for these molecular ensembles in order to predict their functional properties, identify regularity of influence the composition and structure of these systems on studied properties. popup.description2 The object of research is the complex formation of bis(benzoazacrown ethers) with flexible linkers with diamine dichlorides. The aim of the work is the synthesis and study of the complex formation of bis(benzoazacrown ethers) with flexible linkers from dichlorides and diamines for possible use as sensors. Interaction of benzoase-15-crown-5 with ditosylates of the corresponding glycols in acetonitrile in the presence of potassium carbonate or acylation of benzoase-15-crown-5 with α,ω-alkane dicarboxylic acids in a mixture of dioxane and chloroform in the presence of N-hydroxybenzotriazole and dicyclohexylcarbodiimide with the formation of macrocyclic diamides and their subsequent reduction with diisobutylaluminum hydride in tetrahydrofuran yielded bis(benzoazacrown ethers) with methylene or polyoxyethylene chains. The object of research is the synthesis of macroheterocycles with aromatic and heteroaromatic fragments.The aim of the work is to investigate the possibility of using 1,2-bis((1H-benzo[d]imidazol-2-yl)methoxy)benzene in the synthesis of new derivatives of dibenzimidazo crown ethers that differ in the location of the donor centers and the size of the cyclic cavity. The object of research is the interaction of silicon monoxide with germanium dioxide and the effect of boron oxide additives on it with the formation of nanostructures. Orthoborates doped with Cr3+ ions with the MBO3 calcite structure (M= Sc, In, Lu) were synthesized by means of solid-phase reactions. The reasons for the shift of the maximum of the luminescence band (λmax) of Сr3+ ions (transition 4T2→ 4A2) in borates with a calcite structure were analyzed: from λmax= 805-810 nm for MBO3 (M= Sc, In) to λmax= ~850 nm in the case of LuBO3. 1D-QSPR models for predicting the standard enthalpy of formation of oxygen-containing inorganic compounds and their mixtures were constructed and verified.
