About the event

On 7 September at 15:00 p.m. (Moscow time)

Speaker: M. Fátima C. Guedes da Silva, Associate Professor of Instituto Superior Técnico, Universidade de Lisboa, Portugal.

This presentation will cover non-covalent interactions between atoms/molecules, a subject of global interest since, despite their low intensity (much lower than conventional covalent bonds), they can markedly influence the design, construction, synthesis, and stability of chemical structures, as well as their physico-chemical properties and applications.

Specific cases of hydrogen bonds will be highlighted, namely those assisted by resonance (RAHB) and by charge (CAHB), and how such contacts can be adjusted by the pH of the medium and temperature, influencing the generation of building blocks in supramolecular aggregates, the resolution of isomers, reactivity, etc.

Halogen (Ha) and chalcogen (Ch) bonds, which are much less known, will also be considered. These contacts are based on the existence of regions with positive electrostatic potential (sigma-holes) along covalent bonds involving these atoms. Such interactions allow the creation of new types of materials with unique properties and/or with various applications.

Participants: students, postgraduates and scientific-pedagogical workers of the faculty of Sciences of RUDN and other Universities.
