Impact of biogenic very short-lived bromine on the Antarctic ozone hole during the 21st century [PDF]
, 2016 Active bromine released from the photochemical decomposition of biogenic very short-lived bromocarbons (VSL_Br ) enhances stratospheric ozone depletion. Based on a dual set of 1960-2100 coupled chemistry-climate simulations (i.e. with and without VSL Br )

Halogen Bonding in Nucleic Acid Complexes [PDF]
, 2017 Halogen bonding (X-bonding) has attracted notable attention among noncovalent interactions. This highly directional attraction between a halogen atom and an electron donor has been exploited in knowledge-based drug design. A great deal of information has been gathered about X-bonds in protein-ligand complexes, as opposed to nucleic acid complexes. Here

Hierarchy in the halogen activation during surface-promoted Ullmann coupling [PDF]
ChemPhysChem 2019, 20, 2305, 2020 Within the collection of surface-supported reactions currently accessible for the production of extended molecular nanostructures under ultra-high vacuum, Ullmann coupling has been the most successful in the controlled formation of covalent single C-C bonds. Particularly advanced control of this synthetic tool has been obtained by means of hierarchical

(15-crown-5)BiI$_3$ as a Building Block for Halogen Bonded Supramolecular Aggregates [PDF]
arXiv, 2020 We present the synthesis and characterization of (15-crown-5)BiI$_3$ (1) and (15-crown-5)BiI$_3$*0.5TIE (2), a halogen bonded adduct with tetraiodoethylene (TIE), a typical halogen bond donor. Our results show that crown ether complexes of main group metal halides can be employed as halogen bond acceptors for the synthesis of new supramolecular ...

Instantaneous Clear Sky Radiative Forcings of Halogenated Gases [PDF]
arXiv, 2023 The clear sky instantaneous radiative forcings of the 14 halogenated gases previously shown to have the largest contribution to global warming, were found. The calculation used the absorption cross sections for the halogenated gases which are assumed to be independent of temperature as well as over 1/3 million line strengths for the 5 naturally ...

Advanced Functional Materials, EarlyView.An asymmetric non‐fullerene acceptor BTP‐FT is developed by extending the end group of Y6‐BO with thiophene. The conformation of the molecule is determined by the noncovalent F···S interaction as demonstrated by 2D NMR and simulations. An efficiency of 18.39% is achieved in the resulting ternary solar cells processed from toluene.
