EVALUATIONS CONCERNING THE HALOGEN BOND AND HYDROGEN BOND RELATIONSHIP [PDF]
, 2020 The chemical advances of this century are likely to be driven by the ability to predict and control noncovalent interactions. While the hydrogen bond continues to captivate the interests of scientists, the development of non-traditional noncovalent ...

Halogen Bond Involving Hypervalent Halogen: CSD Search and Theoretical Study
, 2016 The Cambridge Structure Database search shows that there are over seventy crystal structures containing halogen bonds in which hypervalent halogens, not monovalent halogens as usual, behave as acceptors of electron density. The nature of the halogen bond

Chloride Ions: Essential Agents for Achieving Spontaneous Delamination of MXene
Advanced Materials, EarlyView.This work first identifies chloride ions as essential agents for spontaneous MXene delamination. Without Cl−, etched Ti3C2Tx remains multilayered; with Cl−, interlayer modification enables Li+ intercalation and osmotic swelling. The SPEED process couples HF‐assisted Al extraction, Cl−‐mediated interlayer expansion, and Li+‐driven swelling to produce ...

2D Abrupt Nano‐Junctions Blending sp–sp2 Bonds on Atomically Precise Heterostructures
Advanced Materials, EarlyView.A lateral heterostructure between atomically precise sp–sp2$^2$ metalated graphdiyne and sp2$^2$ graphene nanoribbons is realized by on‐surface synthesis and investigated by STM and DFT. The impact of on‐surface synthesis byproducts on covalent junction formation yield is unveiled.

Halogen Bonding in Crystal Engineering
, 2012 The structural features of a molecule are determined by the covalent bonds within the molecule. Modification of the structure requires the breaking and creation of covalent bonds. Similarly, the intrinsic reactivity of a molecule arises from the covalently bonded functional groups and active sites on a molecule.

Halogen-bonded cocrystallization with phosphorus, arsenic and antimony acceptors
Nature Communications, 2019 Halogen bonding can be exploited for the design of functional supramolecular materials, but heavier elements that are known to accept a halogen bond remain limited.
