Halogen and Hydrogen Bonding in Halogenabenzene/NH₃ Complexes Compared Using Next-Generation QTAIM

Molecules, 2019
Next-generation quantum theory of atoms in molecules (QTAIM) was used to investigate the competition between hydrogen bonding and halogen bonding for the recently proposed (Y = Br, I, At)/halogenabenzene/NH3 complex. Differences between using the SR-ZORA

π covalency in the halogen bond

Nature Communications, 2020
Current models of halogen bonding describe the σ-symmetric component of this interaction but do not contemplate the possibility of π-covalency. Here the authors provide experimental and computational evidence of π-covalency in halogen bonds involving ...

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.
