International Research Laboratory «Non-valent Interaction in Materials Chemistry»

Scientific results:

As part of the work performed, a wide range of studies were carried out, covering such areas as the chemistry of halogen bonds in organic radicals, the study of halogen bonds using theoretical methods and approaches, and also proposed new practically significant materials based on halogen bonds and catalysts for the most important transformations in organic synthesis.

Based on these works, the following conclusions can be drawn:

1. New knowledge was obtained about the features of the formation of supramolecular assemblies from free radical synthons containing donors and acceptors of halogen interactions, and the influence of supramolecular assembly on magnetic interactions in the resulting systems was shown.
2. The phenomenon of the formation of optically anisotropic systems based on the supramolecular organization of nitronyl nitroxide derivatives was discovered and approaches to obtaining crystals of this type were developed.
3. Methods for obtaining new active catalysts based on cyclic iodonium salts were developed and a method was proposed for assessing their activity using experimentally obtained rate constants for the Michael addition reaction.
4. Methods for the preparation of iodonium salts of the heterocyclic series have been developed and their complexation with noble metals has been studied to create hybrid catalytic systems.
5. Methods and approaches to the preparation of new iodonium salts - reagents for the covalent immobilization of donors of non-valent interactions for the creation of catalytic systems and hybrid materials with a molecular recognition function - have been proposed.
6. Fundamental aspects of the formation of supramolecular assemblies of a wide range of perrhenates have been studied and mechanisms for their identification using X-ray photoelectron spectroscopy have been proposed;
7. Methods have been proposed for the precipitation of platinum group metal tetracyanates using iodonium salts containing a nitrophenyl substituent;
8. A design has been proposed and a method has been developed for producing a hybrid material based on mesoporous gold films with a UiO-66-I type MOCP immobilized on the surface to create a recognition layer. Based on the obtained method, a selective SERS sensor was developed for highly sensitive detection of chloroarenes in the presence of other organic contaminants.

Organizational and infrastructural changes:

By order of the university, two premises with a total area of ​​108.4 m2 were allocated for the implementation of the project. Room No. 1 is divided into two parts: an office to accommodate laboratory staff and an area for conducting experiments. In the office part of the premises there is a workplace for the leading scientist and members of the research team, equipped with office furniture and office equipment.

The experimental area was created mainly for the operation of the key research instrument - the single-crystal diffractometer with a microfocus source (single crystal X-ray diffractometer TD 5000).

Room No. 2 is intended for conducting experiments (laboratory) and is equipped with equipment, including that purchased with grant funds.
