Production of active components of organic light-emitting diodes with candle light characteristics (Candle Light-Style Organic Light Emitting Diode)
Search for optimal structures and targeted synthesis of dyes based on chalcogenazole containing heterocyls to create LEDs that are physiologically safe. Such LEDs, thanks to an innovative design and a combination of new specially synthesized phosphors, have practically no harmful radiation in the blue region of the spectrum, and the color characteristics of their radiation are similar to the light characteristics of the flame of ordinary candles. The advantage of such devices is also the absence of rare and noble metals in their composition, such as iridium and platinum (the basis of modern industrial phosphors for OLED devices), and the relative simplicity of the design as a whole.

New approaches to polyserase-containing heterocycles
New approaches to the synthesis of polyserase-containing heterocycles containing several sulfur atoms and a nitrogen atom based on the reaction of sulfur monochloride complexes and nitrogen-containing bases are being investigated. At the moment, a number of new heterocyclic systems have been obtained, including 1,2- and 1,4-thiazines, thiophenes, monocyclic and condensed 1,2-dithiols and 1,2,3-dithiazoles, 1,2,3,4,5-pentathiepines, 1,2,3,4,5,6,7-heptathiocanes, etc. The polyserase-containing heterocyclic compounds synthesized by us (1,2-dithiols, 1,2,3,4,5-pentathiepines and 1,2,3-dithiazoles) show high anticancer, antimicrobial and antifungal activities.Synthesized 1,2,3,4,5-pentathiepines have been studied as a cathode material for batteries; condensed 1,4-dithiines have been proposed as multi-purpose components for photoreceptors.

New series of organic sensitizers based on chalcogenase-containing heterocycles

New series of organic sensitizers based on chalcogenase-containing heterocycles
The search for new effective organic components for Dye-sensitized solar cells (DSSCs) based on the D-A-π-A strategy, which consists in the introduction of an additional acceptor group (A) between the donor (D) and the π bridge, in the role of which chalcogenase-containing heterocycles act. Development of organic sensitizers of a more complex design to create more effective DSSCs.

The general mechanism of action of polysulfide heterocycles against feline immunodeficiency virus
Methods for the synthesis of polysulfide heterocycles are being developed, which have a common mechanism of action and high selectivity against the feline immunodeficiency virus, which is the closest analogue of the human immunodeficiency virus. It has already been established that compounds of different heterocyclic structures: bis(dithiolo)thiazines, bis(dithiolo)pyrroles, tetrathiocines, dithiazoles, dithioloindoles, pentathiepines and thiaselenazoles are promising antispid compounds, which is of significant value for the development of not only chemical, but also biological sciences.
