“…It is reported that 2,2 0 -dipyridyl decreases the reaction rate of Cu 2+ reduction via the adsorption on the Cu surface. [40][41][42] The contribution of 8.5 kJ mol À1 to k g is about 33% decrease in the reaction rate, indicating that the adsorbed 2,2 0dipyridyl on Cu also affect the pre-exponential factor that contains the collision rate of Cu 2+ on the Cu surface and a steric factor (proper orientation of the collision for the reaction).…”

The electronic effects in supramolecular systems are a great challenge for computational chemistry, and the understanding of ligand-protein interactions driven by halogen bonds can be limited by molecular mechanics point of view. In fact, the variations of the halogen bond acceptors, such as an aromatic ring and electrons lone pairs, restrict the classical approximations even more. Our work enhances the statement that halogen bonds are led mainly by orbital interactions via σ*. Nonetheless, we have pointed a straight relationship between the maximum ESP value on the σ-hole and the LUMO energy levels of the halogen bond donor. In line with this scenario, the current work introduces a new promising empirical potential based on quantum parametrizations able to describe general halogen bonded systems. The new parameters allow force fields to detect variations on the molecular electronic structure of halogenated organic compounds to improve the description of fluorine, chlorine, and bromine in halogen bonds.

“…Thanks to the presence of sterically unhindered bromine atom in CP‐1 which led to the delocalized C−Br⋅⋅⋅π type halogen bonding and long range ordered H‐type π‐π stacking that stabilized the triplet excited state for long‐lasting room temperature phosphorescence and created large electron pathways for efficient charge transport. Halogen bonding has also been successfully employed in influencing the supramolecular 2D layer formation in azobenzene‐functionalized Zn(II)‐based coordination networks [125] …”

Polymers have long been known to us for their versatile utility in our daily lives. With many years of successful advancement in controlled polymer synthesis and supramolecular chemistry, currently an amalgamation of these two fields is becoming increasingly important for generating modern‐day emerging polymeric materials. Hydrogen bonding and other noncovalent interactions like π‐stacking, host‐guest interaction, electrostatic interaction, metal‐ligand coordination have been explored much to this context, unlike the recently emerged halogen bonding, which indeed shows advantageous features like superior hydrophobicity, directionality and polar solvent resistance compared to ubiquitous hydrogen bonding. Hence, rendering these properties of halogen bonding into polymeric domain for generating functional materials for application in advance nanotechnologies is highly desirable. In the recent years, substantial progress has been made in fulfilling this challenging goal. This is evident from the escalating number of scientific publications in this research area every year. In this minireview, we have summarized the most recent developments in the field of halogen bonded polymeric assemblies and supramolecular polymers and discussed them in the context of their emerging materials properties and functions. Emphasis is given on highlighting various design criteria adopted in crystal engineering, covalent and supramolecular polymers in the past five years for constructing diverse organic functional materials, viz. liquid crystals, photoresponsive and photochromic materials, biomaterials and gels, self‐healing materials and many others by virtue of this highly directional supramolecular tool. In conclusion, a brief perspective on the advantages, challenges and future prospects in this rapidly growing field of research is discussed.
