“…After network formation, the chemical composition of polymer chains and distribution of crosslinks in MHGs are fixed. This can be quite the opposite in SHGs, where monomer (gelator) exchange dynamics (on the second to hour timescale) within the fiber are mainly dictated by interaction strength. Several cases now exist where, either before or after initial network formation from a mixture of gelators, the gelators selectively form interpenetrating or phase‐separated networks of homopolymer fibers through a self‐sorting process.…”

Herein, we lay out the pros and cons of constructing (hydro) gels from polymer networks held together by noncovalent interactions or covalent bonds. Hydrogel materials currently find many applications in personal care products, biomaterials, coatings, and plant fertilizers. They have a large potential for future application in sensing, drug delivery, soft robotics, and biohybrid or biointerfacing materials. To scientists working in those fields, the choice of material type may depend heavily on the intended application and associated required properties. There, it can be useful to consider a generalized overview and comparison of hydrogel structure, properties, and performance in various scenarios.Hydrogels are fascinating soft materials with unique properties. Many biological systems are based on hydrogel-like structures, underlining their versatility and relevance. The properties of hydrogels strongly depend on the structure of the building blocks they are composed of, as well as the nature of interactions between them in the network structure. Herein, gel networks made by supramolecular interactions are compared to covalent macromolecular networks, drawing conclusions about their performance and application as responsive materials.

“…The studies mentioned above were performed in water to explore the potential use of BTA polymers for biomedical applications. However, methods that enable super resolution imaging of supramolecular structures, such as, BTA fibres in methyl cyclohexane in organic media have also been developed [21][22][23] In addition to BTAs, other families of supramolecular polymers have been studied using nanoscopy, including ureidopyrimidinone (Upy)-based polymers and peptide amphiphiles 24 . In both cases the mechanism as well as the kinetics of monomer exchange was unveiled and the structure-dynamics relationships highlighted.…”

Theoretical and experimental studies have elucidated the bonding mechanism in hydrogen bonds as an electrostatic interaction, which also exhibits considerable stabilization by charge transfer, polarization, and dispersion interactions. Therefore, these components have been used to rationalize the differences in strength of hydrogen-bonded systems. A completely new viewpoint is presented, in which the Pauli (steric) repulsion controls the mechanism of hydrogen bonding. Quantum chemical computations on the mismatched DNA base pairs CC and GG (C=cytosine, G=guanine) show that the enhanced stabilization and shorter distance of GG is determined entirely by the difference in the Pauli repulsion, which is significantly less repulsive for GG than for CC. This is the first time that evidence is presented for the Pauli repulsion as decisive factor in relative hydrogen-bond strengths and lengths.
