Halogen-bonded shape memory polymers
Nature Communications, 2022 Halogen bonding is widely adopted in organic synthesis and supramolecular crystal engineering but application of halogen bonding in the design of stimuli-responsive materials is challenging.

“Anti-Electrostatic” Halogen Bonding [PDF]
Angewandte Chemie International Edition, 2020 Halogen bonding (XB) is often described as being driven predominantly by electrostatics, and thus adducts between anionic XB donors (halogen-based Lewis acids) and anions seem counterintuitive. Such “anti-electrostatic” XBs have been predicted theoretically, but there are currently no experimental examples based on organic XB donors. Herein, we report

Activation of a Metal‐Halogen Bond by Halogen Bonding [PDF]
Angewandte Chemie International Edition, 2020 Abstract In recent years, the non‐covalent interaction of halogen bonding (XB) has found increasing application in organocatalysis. However, reports of the activation of metal‐ligand bonds by XB have so far been limited to a few reactions with elemental iodine or bromine. Herein, we present the activation of metal‐halogen bonds by two

Astatine Facing Janus: Halogen Bonding vs. Charge-Shift Bonding
Molecules, 2021 The nature of halogen-bond interactions was scrutinized from the perspective of astatine, potentially the strongest halogen-bond donor atom. In addition to its remarkable electronic properties (e.g., its higher aromaticity compared to benzene), C6At6 can

Direct arylation reaction of heteroarenes mediated by photoinduced electron transfer
Journal of Photochemistry and Photobiology, 2023 Electron donor–acceptor (EDA) complexes are interesting chemical species that function as molecular complexes. In this context, chemists have actively studies the use of halogen bonding as a noncovalent interaction in photochemistry.

Type II halogen···halogen contacts are halogen bonds [PDF]
IUCrJ, 2013 Cl/Br/I alternative substitutions in a series of dihalophenols indicate that type I and type II halogen···halogen contacts have different chemical nature. Only the latter ones qualify as true halogen bonds, according to the recent IUPAC definition.

Halogen Bonding in Two‐Dimensional Crystal Engineering
ChemistryOpen, 2020 Halogen bonds, which provide an intermolecular interaction with moderate strength and high directionality, have emerged as a promising tool in the repertoire of non‐covalent interactions.

Intramolecular halogen–halogen bonds?
Physical Chemistry Chemical Physics, 2013 By analysing the properties of the electron density in the structurally simple perhalogenated ethanes, X3C-CY3 (X, Y = F, Cl), a previously overlooked non-covalent attraction between halogens attached to opposite carbon atoms is found. Quantum chemical calculations extrapolated towards the full solution of the Schrödinger equation reveal the complex ...

Antibiotics, 2023 Novel bacterial topoisomerase inhibitors (NBTIs) are a new class of antibacterial agents that target bacterial type II topoisomerases (DNA gyrase and topoisomerase IV). Our recently disclosed crystal structure of an NBTI ligand in complex with DNA gyrase
