Competition between Halogen, Hydrogen and Dihydrogen Bonding in Brominated Carboranes [PDF]

, 2016
Halogen bonds are a subset of noncovalent interactions with rapidly expanding applications in materials and medicinal chemistry. While halogen bonding is well known in organic compounds, it is new in the field of boron cluster chemistry.

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.
