Chalcogen bonding in the solid-state structures of 1,3-bis(benzimidazoliumyl)benzene-based chalcogen-bonding donors

Acta Crystallographica Section C Structural Chemistry, 2023
1,3-Bis(benzimidazoliumyl)benzene-based chalcogen-bonding catalysts were previously successfully applied in different benchmark reactions. In one of those examples, i.e. the activation of quinolines, sulfur- and selenium-based chalcogen-bonding catalysts showed comparable properties, which is unexpected, as the selenium-containing catalysts should show

Escaping the Scaling Relationships in Oxygen Reduction Catalysis: Implications for PEM Fuel Cells

Advanced Materials, EarlyView.
Escaping the scaling relationships of the oxygen reduction reaction is vital for hydrogen fuel cells. This outlook examines how interfacial heterogeneity, spanning the subsurface lattice, chemisorption layer, and near‐interface solvation volume, mechanistically decouples intermediate binding energetics.

Universal Strategy for Phase‐Selective Synthesis of Monolayer TMDs via Colloidal Chemistry

Advanced Materials, EarlyView.
ABSTRACT Colloidal synthesis of monolayer transition metal dichalcogenides (TMDs) remains challenging regarding uniform size, thickness, and crystalline phase. While significant progress has been made in phase engineering, a unified chemical strategy for on‐demand selection of both 2H and 1T′ phases across multiple TMD systems within a single chemical ...

Radiation‐Matter Interaction in Chemical Vapor Deposition‐Grown Two‐Dimensional Tungsten Disulfide

Advanced Materials Interfaces, EarlyView.
Gamma irradiation tunes the magnetic properties of CVD‐grown WS2 material. Moderate irradiation doses induce low‐temperature ferromagnetic‐like behavior, whereas higher doses suppress the magnetic response because of increased defect formation. These findings provide insight into defect‐mediated magnetism in 2D TMDs and could be relevant to future ...

Sulfur-mediated chalcogen versus hydrogen bonds in proteins: a see-saw effect in the conformational space

QRB Discovery, 2023
Divalent sulfur (S) forms a chalcogen bond (Ch-bond) via its σ-holes and a hydrogen bond (H-bond) via its lone pairs. The relevance of these interactions and their interplay for protein structure and function is unclear.

Understanding Interfacial Photoswitching Mechanisms in Atomically‐Thin TMD‐Spiropyran Hybrids

Advanced Materials Technologies, EarlyView.
Photochromic molecules can effectively modulate the optoelectronic properties of atomically thin transition metal dichalcogenide semiconductors. Spiropyran that switches its chemical configuration upon alternating UV and visible irradiation enables light‐programmable optoelectronic devices.

Theoretical Investigations on Heteronuclear Chalcogen−Chalcogen Interactions:  On the Nature of Weak Bonds between Chalcogen Centers

Inorganic Chemistry, 2007
To understand the intermolecular interactions between chalcogen centers (O, S, Se, Te), quantum chemical calculations on model systems were carried out. These model systems were pairs of monomers of the composition (CH3)2X1 (X1 = O, S, Se, Te) as the donors and CH3X2Z (with X2 = O, S, Se, Te and Z = Me, CN) as the acceptors.
