Chalcogen⋅⋅⋅π Bonding Catalysis
Angewandte Chemie, 2021AbstractWhile the presence of sulfur⋅⋅⋅π bonding interaction is a general phenomenon in the biological systems, the exploitation of this noncovalent force in a chemical process yet remains elusive. Herein, we describe the concept of chalcogen⋅⋅⋅π bonding catalysis that activates molecules of π systems through the interaction between chalcogen and π ...

Chalcogen bonding in materials chemistry
Coordination Chemistry Reviews, 2020Abstract This review examines recent literature in search for evidence of the influence that chalcogen bonding has on the structure and properties of functional materials. Key examples from research on charge transfer salts, neutral heterocyclic free radicals, and paramagnetic coordination compounds are highlighted as intermolecular interactions are ...

Supramolecular Capsules: Strong versus Weak Chalcogen Bonding
Angewandte Chemie International Edition, 2018AbstractResorcin[4]arene cavitands containing either 2,1,3‐benzotelluradiazole or 2,1,3‐benzothiadiazole motifs were dimerized to supramolecular capsules by chalcogen bonding. Their respective behavior varied depending on the interaction strength of the chalcogen bonds with Te forming strong interactions and S weak interactions. The tremendous strength

Dual Chalcogen–Chalcogen Bonding Catalysis
Journal of the American Chemical Society, 2020The noncovalent S···O bonding interaction is an evolutionary force that has been smartly exploited by nature to modulate the conformational preferences of proteins. The employment of this type of weak noncovalent force to drive chemical reactions is promising yet remains largely elusive.

Chalcogen-Bonding Supramolecular Polymers
The Journal of Organic Chemistry, 2020Exploring unknown supramolecular interacting forces to create novel supramolecular materials is an eternal theme of supramolecular science. Here, we first report a new family of supramolecular polymers formed by unconventional chalcogen-bonding interactions. A class of chalcogen-containing macrocyclic receptors, termed as chalcogena[4]arene (ChA[4], Ch

A Porous Chalcogen-Bonded Organic Framework
Journal of the American Chemical Society, 2021The manner of bonding between constituent atoms or molecules invariably influences the properties of materials. Perhaps no material family is more emblematic of this than porous frameworks, wherein the namesake modes of connectivity give rise to discrete subclasses with unique collections of properties.

Chalcogen Bonding: An Overview
Angewandte Chemie International Edition, 2018AbstractIn the last few decades, “unusual” noncovalent interactions like anion‐π and halogen bonding have emerged as interesting alternatives to the ubiquitous hydrogen bonding in many research areas. This is also true, to a somewhat lesser extent, for chalcogen bonding, the noncovalent interaction involving Lewis acidic chalcogen centers.
