IV International Symposium

“Noncovalent Interactions in Synthesis,

Catalysis, and Crystal Engineering”

(NCI-2026)

Progress in the study of non-covalent interactions and their influence on chemical processes has been particularly noticeable over the last two decades. It can be expected that achievements in 21st-century chemistry will be largely determined by non-covalent interactions. The symposium is intended to be a platform for regular meetings of researchers studying non-covalent interactions using different methods and with different goals, to exchange latest data, share experience and points of view.

Non-covalent interactions are widespread in nature and contribute to the strength (cohesion) of chemical systems. Compared to covalent bonds, intra- and intermolecular non-covalent interactions are generally weaker and characterized by much lower energy and directionality, which is reflected in the term ‘non-covalent'. The aim of the Symposium is to discuss various aspects of the manifestation of non-covalent interactions in both the solid state and the liquid state, experimental and theoretical methods for studying non-covalent interactions, their influence on the reactivity and catalytic transformations of chemical compounds, as well as the role of non-covalent interactions in the formation of supramolecular structures, in crystal design and in chemical synthesis of tectons for the construction of supramolecular systems.

The Symposium will be held in a traditional ‘offline' format. Online participation is only available for invited speakers from abroad. The Symposium program includes plenary lectures, keynote lectures, oral and poster presentations, as well as flash presentations.

The working languages are Russian and English. Abstracts should be submitted in English.

History:

The symposium will be held in the center of St. Petersburg, at the premises of St. Petersburg State University (SPbU).

The opening ceremony and the first day of the Symposium will take place in the conference hall of the main historical building of SPbU — the Twelve Collegia building (Mendeleevskaya lane, 2), and subsequent sessions will be held in the neighboring University Centre building (Birzhevaya lane, 6).

Participants are responsible for booking and paying for their own accommodation.

Note: there are many hotels of various sizes, quality and price levels in the center of St. Petersburg, but it should be noted that the end of June is the peak of the tourist season and hotel room’s availability is limited, with prices rising significantly. Therefore, the organizing committee recommends that you arrange your accommodation as early as possible.
 
The local organizing committee is offering logistic help with hotel bookings for foreign participants. Please contact Prof. Dr. Peter Tolstoy peter.tolstoy@spbu.ru if such help is needed.
