The Basics of Covalent Bonding in Terms of Energy and Dynamics [PDF]

open access: yesMolecules, 2020
We address the paradoxical fact that the concept of a covalent bond, a cornerstone of chemistry which is well resolved computationally by the methods of quantum chemistry, is still the subject of debate, disagreement, and ignorance with respect to its physical origin. Our aim here is to unify two seemingly different explanations: one in terms of energy,

Hydrogels Based on Dynamic Covalent and Non Covalent Bonds: A Chemistry Perspective [PDF]

open access: yesGels, 2018
Hydrogels based on reversible covalent bonds represent an attractive topic for research at both academic and industrial level. While the concept of reversible covalent bonds dates back a few decades, novel developments continue to appear in the general research area of gels and especially hydrogels.

Water-stable boroxine structure with dynamic covalent bonds

open access: yesNature Communications, 2023
Abstract Boroxines are significant structures in the production of covalent organic frameworks, anion receptors, self-healing materials, and others. However, their utilization in aqueous media is a formidable task due to hydrolytic instability.
