Model imidazole compounds were synthesized, one of which does not contain crown ether fragments, and the other contains one crown ether ring, as well as two new bis(benzocrown ethers) with o-nitro substituents in the imidazole fragment. The most stable complexes (lgK21 6–9) have a composition of 2:1 and are formed with all cations by almost all ligands, with a few exceptions. Preparative methods for the synthesis of new derivatives of 18, 19, 20, and 40-membered dibenzimidazo crown ethers containing fragments of diatomic phenols by cyclization of 1,2-(benzimidazolyl-2-oxomethyl)-ethane with ditosylates of ethers based on pyrocatechin, resorcinol, hydroquinone. The interaction of silicon monoxide with germanium dioxide and zinc oxide under different conditions with the formation of nanostructures was investigated. Micro- and nanosized orthoborates of indium and scandium MBO3 doped with Сr3+ ions were obtained by solid-phase reactions and thermolysis of an amorphous precursor, respectively. It is shown that the quantum efficiency of luminescence of micro-sized samples of InBO3:Cr3+ reaches 0.60-0.70, while for nano-sized samples of InBO3:Cr3+ this parameter is only 0.23-0.30. Collected information for oxygen-containing inorganic compounds - oxides (simple, complex, mixed) regarding the standard enthalpy of formation (∆Но298), which under standard conditions is a measure of thermodynamic stability of compounds, a quantitative expression of their energy content.
