Crystal Structures and Intermolecular Interactions in α$\alpha$‐ and β$\beta$‐phosgene

Angewandte Chemie, EarlyView.
Despite its notorious reputation as a war gas, phosgene (COCl2${\rm COCl}_2$) is one of the most important intermediate chemicals in industry. In this study, we present the crystal structures of two phosgene polymorphs as deduced from powder neutron diffraction and show which intermolecular interactions stabilise the different modifications.

Can Europium Atoms form Luminescent Centres in Diamond: A combined Theoretical-Experimental Study

, 2019
The incorporation of Eu into the diamond lattice is investigated in a combined theoretical-experimental study. The large size of the Eu ion induces a strain on the host lattice, which is minimal for the Eu-vacancy complex.

Highly Selective Adsorption of Fluorinated Gases by Porous Organic Cages – Effects of Fluorinated Side‐Chains

Advanced Materials, EarlyView.
A systematic study of a series of porous organic cages with perfluorinated alkyl side‐chains of different lengths is presented. The structure‐property relationship of the various cages on gas sorption of highly potent greenhouse gases, such as perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3) is investigated.

Enhanced Selectivity of Chalcogen Bonding over Halogen Bonding Catalyzed C‐glycosylation Through Differentiated Intermediate Activation

Angewandte Chemie, EarlyView.
By harnessing chalcogen bonding (ChB) catalysis, an exclusive access into a highly stereoselective strain‐release C‐glycosylation pathway was discovered. This was surprisingly not replicable by the conceptually similar halogen bonding (XB) catalysis.
