About this collection
Noncovalent interactions (hydrogen, noble gases, halogen, chalcogen, pnictogen, tetrel and triel bonds, as well as cation-π, anion-π, lone pair-π, π-π stacking, agostic, pseudo-agostic, anagostic, dispersion-driven, lipophilic, etc.) concern weak forces of attraction formed between different molecules (intermolecular) or fragments of the same molecule (intramolecular). While these weak interactions were firstly taken into consideration by van der Waals in 1873, the understanding of their crucial role in synthesis, catalysis, crystal engineering, pharmaceutical design, molecular biology, molecular recognition, materials, etc. has been increasingly explored in the last few decades. Thus, it is timely to establish a general/regular series of International Conferences on Noncovalent Interactions (ICNI), the first of which is to be held on 2-6 September 2019 in Lisbon. The conference aims to bring together scientists from around the world working on this field in order to exchange ideas, discuss recent advances and future directions/plans.
