A review of the work in the field of design, study of properties, and application of liquid crystal materials and acrylamide porphyrin polymers, performed at the Department of Chemistry and Technology of High-molecular Compounds, in the laboratory of Supramolecular and liquid crystal systems and in the laboratory of Polymer materials of the Research Institute of Macroheterocyclic compounds of the Ivanovo State University of Chemical Technology over the past 10 years, is presented. Synthetic methods were developed, mesogenic compounds and mixed liquid crystal compositions based on classical and supramolecular mesogens doped with additives containing polar, amphiprotic and chiral groups were obtained and studied. The mechanisms of chiral transport in the mesophase were studied. The results on the use of liquid crystals as light and heat stabilizers of polymeric materials are presented. Stationary phases for gas-liquid chromatography based on supramolecular mesogens, macroheterocyclic compounds with high structural selectivity with respect to various isomers were developed. Methods have been developed for the synthesis of water-soluble porphyrin polymers and porphyrin-containing hydrogels based on acrylamide and synthetic porphyrin monomers, realizable both under thermal heating and under microwave radiation. It is shown that a change in the ratio and nature of the components, as well as the polymerization conditions in the synthesis of porphyrin polymers provides targeted control of the properties of the resulting compounds. The molecular-mass and spectral characteristics of the obtained polymers, their surface morphology and sorption properties of porphyrin-containing acrylamide hydrogels are investigated.

“…Макрогетероциклические соединения (Мс) проявляют нелинейно-оптические, люминесцентные, жидкокристаллические, противоопухолевые, антибактериальные свойства, которые позволяют широко использовать подобные молекулы в технике и медицине [1][2][3][4][5][6][7][8]. Все большее значение приобретают Мс с расширенной π-электронной системой и координационной полостью, которая способна вмещать один атом металла большого радиуса или несколько атомов меньшего радиуса.…”

This article is devoted to a selection of the most effective preparative method for the synthesis of bis(5-amino-1,3,4-thiadiazole-2-yl)alkanes. These compounds are binuclear diamines consisting of symmetrical 1,3,4-thiadiazole fragments connected by alkyl spacers of various lengths. The structures of the obtained compounds were determined by IR spectroscopy, mass-spectrometry and elemental analysis. The possibility of using these molecules as precursors for the synthesis of macroheterocyclic compounds with expended coordination cavity consisting of six small cycles was demonstrated. Optimal synthesis conditions of bis(5-amino-1,3,4-thiadiazole-2-yl)ethane and bis(5-amino-1,3,4-thiadiazole-2-yl)butane were found by variation of reaction time and temperature. Virtual screening of the obtained compounds was carried out in order to predict antibacterial and biological activities as well as toxic properties of the targeted products. On the basis of the known literature data on polynuclear diamines, the exhibition of the liquid crystal properties of the synthesized molecules is supposed.
