Halogen Bonding in Crystal Engineering [PDF]

Acta Crystallographica Section A Foundations of Crystallography, 2005
The term halogen bonding encompasses any non-covalent interaction involving halogens as electrophilic species. High strength and directionality are the remarkable features of halogen bonding that fully justify its use as a primary intermolecular interaction to dictate molecular self-assembly processes.

Studies of Halogen Bonding Induced by Pentafluorosulfanyl Aryl Iodides: A Potential Group of Halogen Bond Donors in a Rational Drug Design

Molecules, 2019
The activation of halogen bonding by the substitution of the pentafluoro-λ6-sulfanyl (SF5) group was studied using a series of SF5-substituted iodobenzenes.

Solid-State Fluorescence Enhancement of Bromine-Substituted Trans-Enaminone Derivatives

Organic Materials, 2020
Halogen bonding, as a kind of intermolecular interaction, has rarely been used to tune solid-state emission properties of luminescent materials, especially fluorescent materials.

Tailoring the strength and number of halogen bonds toward room temperature phosphorescent micro‐cocrystals

Nano Select, 2021
Organic room temperature phosphorescent materials are very limited to date. Halogen bonding interactions not only promote the intersystem crossing process, but also act as cement and dilute solution, preventing the aggregation induced quenching.

On the Importance of Halogen Bonding Interactions in Two X-ray Structures Containing All Four (F, Cl, Br, I) Halogen Atoms

Crystals, 2021
This manuscript reports the synthesis and X-ray characterization of two octahydro-1H-4,6-epoxycyclopenta[c]pyridin-1-one derivatives that contain the four most abundant halogen atoms (Ha) in the structure with the aim of studying the formation of Ha···Ha

Transmembrane Halogen-Bonding Cascades

Journal of the American Chemical Society, 2013
Halogen bonds have recently been introduced as ideal to transport anions across lipid bilayer membranes. However, activities obtained with small transporters were not impressive, and cyclic arrays of strong halogen-bond donors above a calix[4]arene scaffold gave even weaker activities. Here, we report that their linear alignment for anion hopping along

5-Iodo-1-Arylpyrazoles as Potential Benchmarks for Investigating the Tuning of the Halogen Bonding

Crystals, 2020
5-Iodo-1-arylpyrazoles are interesting templates for investigating the halogen bond propensity in small molecules other than the already well-known halogenated molecules such as tetrafluorodiiodobenzene.

Characterising Supramolecular Architectures in Crystals Featuring I⋯Br Halogen Bonding: Persistence of X⋯X’ Secondary-Bonding in Their Congeners

Crystals, 2021
The Cambridge Structural Database was surveyed for crystals featuring I⋯Br secondary-bonding in their supramolecular assemblies occurring independently of other obvious supramolecular synthons and devoid of other halogen bonding interactions.

Halogen Bonds Fabricate 2D Molecular Self-Assembled Nanostructures by Scanning Tunneling Microscopy

Crystals, 2020
Halogen bonds are currently new noncovalent interactions due to their moderate strength and high directionality, which are widely investigated in crystal engineering.
