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 the study includes complex compounds of bis(benzocrown ethers) containing a Tröger’s base fragment; macroheterocycles with aromatic and heteroaromatic fragments; europium sesquioxide; silicon monoxide; scandium complexes with resveratrol; Cr³⁺ ions in orthoborates of group III elements; nanosized metal oxides; and QSAR methodology. The purpose of the work is the synthesis and investigation of the complexation of bis(benzocrown ethers) containing a Tröger’s base fragment; the synthesis of isomeric dibenzimidazo-crown ether compounds; the use of lanthanide ions for the luminescent determination of resveratrol; the analysis of the influence of the electronic structure of compounds on the luminescent properties of Cr³⁺ ions in orthoborates of group III elements; and the construction and validation of QSAR models for predicting the cytotoxicity of metal nanooxides. Crowned Tröger’s bases containing fragments of benzo-15-crown-5, benzo-18-crown-6, and tetrafluorodibenzo-18-crown-6 were synthesized with yields of 71–88%. The stability constants of complexes of bis(benzocrown ethers) with chlorides of polyoxyethylenediamines and selected amino acids were determined. Cyclization of 1,3-bis(benzo[d]imidazolyl-2-oxomethyl)benzene with ditosylates of 1,2-, 1,3-, and 1,4-bis(2-hydroxyethoxy)benzene afforded 19-, 20-, and 21-membered macrocycles, respectively. Diffuse reflectance spectra of the Eu(II) orthosilicate reaction product confirm the occurrence of the reaction, which is consistent with thermodynamic calculations for systems containing elements with variable valence states. The spectral characteristics of resveratrol were determined, and a solid-phase luminescent method for its determination in grape wines and juices was developed using a sorbate of the Sc(III)–resveratrol complex with Brij® 35. Micron-sized indium and scandium orthoborates doped with Cr³⁺ ions were obtained by solid-state reactions. Product Description popup.authors Smola Serhii S. Доценко Володимир Павлович Tetiana I.
