Research interests are development of experimental and theoretical bases of controlled self-assembling of complex organic compounds and construction of low-dimensional functional nanoarchitectures in confined space at nanolevel: at a gas-liquid interface, in films on solid substrates and in nanoengineered capsules.

The author of the concept of nanostructuring of organic compounds at the liquid-gas interface, according to which the structural units of the layer in the general case are not individual molecules (Langmuir approach), but their M-nanostructures formed as a result of self-assembling.  The main provisions are set forth in the works:

A fundamentally new result obtained using the basic principles of the concept is the possibility of the formation of a special type of nanostructures (supermolecules), the intermolecular interactions in which and the properties are radically different from the properties of the starting compounds (Figure 1).

The main directions of the research in the Laboratory

  • Nanoarchitectures of macroheterocyclic compounds formed in confined space at the nanolevel (at the gas-liquid interface, in thin films and in nanoengineered capsules);
  • Supermolecular porphyrin nanomaterials;
  • Reactions in two-dimensional layers at the gas-liquid interface (polymerization, complexation, etc.);
  • Layers and films with the active state of the functional component, thin-film sensors and catalysts;
  • Systems for targeted drug delivery (vitamin B12, chlorin e6, etc.);
  • Structure of floating layers, films and capsules according to X-ray reflectometry (XRR) and Grazing incidence X-ray diffraction (GIXD and GISAXS);
  • Theory of the condensed state. Generalized state equation of a nanostructured floating M-layer

The main scientific results


  • The concept of nanostructuring of complex organic compounds at the gas–liquid interface was proposed and developed [Doctor of Science Dissertation 2012Chapter 18 in Monograph 2019];
  • A model of a nanostructured layer on the surface of the liquid (M-monolayer) was built. The physical basis of model consists in representation of the monolayer as real two-dimensional gas whose structural units can be separate molecules (Langmuir layer) as well as their nanoaggregates (M-layer). Parameters of the model are quantitative characteristics of structure and properties of the layer [Colloid Journal 2008, Journal of Porphyrins and Phthalocyanines 2010];
  • A method for the quantitative analysis of compression isotherms and determination of the structure of the M-monolayer was developed, new characteristics of the structure and properties of the layer and methods for their presentation were introduced. The first M-isotherm and state diagram are determined [J. Porphyrins Phthalocyanines, 2018]. A passport of floating layers containing borders of existence regions and corresponding characteristic of layers of different structure is composed [BioNanoScience, 2017]. Foundations for creation of the knowledge base on floating layers of compounds are developed


  • For the first time, stable 3D nanostructures of the same size of copper porphyrazine, which, when studied by X-ray scattering, manifest themselves as a whole were formed [ACS Langmuir 2008];
  • The first porphyrin supermolecules— unique nanostructures with strong non-covalent intermolecular interactions whose properties are radically different from the properties of the starting compound were discovered (ACS Langmuir, 2018);
  • The formation of vitamin B12 nanostructures in polymer capsules has been established [Colloids and surfaces B: Biointerfaces, 2019]

The significance of the tasks is determined by the fact that the processes of nanostructuring of biologically active compounds, in particular, chlorophyll a derivatives, the most important functions of which, in nature, are carried out precisely in ensembles are studied. Their properties are determined by the structure of the ensemble. Such compounds are actively used in catalysis and in medicine, where their aggregate behavior directly determines the properties of the material.

The results obtained make it possible to use the Langmuir-Blodgett technology as a tool for studying and forming 2D and 3D nanoarchitectures, including supermolecules of organic compounds, carrying out reactions in such layers and obtaining fundamentally new types of nanomaterials on their basis.

Areas of practical application of the results are as follows: (1) nano- and biotechnologies – new methods for obtaining of biomedical nanomaterials based on nanoarchitectures of biologically active compounds; (2) photonics – optical nanomaterials and photosensitizers; (3) ecology – water purification (decomposition of organic impurities); oxidative modification of natural compounds, including natural antioxidants; (4) pharmacology –  new drugs and their targeted delivery.
