From supramolecular polymers to hydrogel materials

Abstract: Supramolecular hydrogels formed by decorating benzene-1,3,5-tricarboxamide (BTA) units with amphiphilic ethylene glycol-based side chains are presented; careful selection of the substituents of the BTAs allows for the tuning of the self-assembly behaviour and hence the mechanical properties of the resultant hydrogel.

“…More recently, benzene‐1,3,5‐tricarboxamide (BTA) has been recognized as a useful multiple hydrogen bonding unit for formation of supramolecular hydrogels. BTA is a disk‐shaped molecule functionalized with hydrophobic alkyl spacers and oligo(ethylene glycols) to increase solubility in polar solvents, such as water .…”

“…In water, BTA uses a combination of its threefold hydrogen bonding, protective hydrophobic pocket, and π–π interactions between the benzene rings to self‐assemble into helical fibers ( Figure 3 ). At high enough concentrations, BTA‐based hydrogels form as a result of cross‐linking of telechelic BTAs, and much like UPy‐based hydrogels, are very sensitive to the ratio between hydrophobic and hydrophilic spacers . Recently, this method of self‐assembly has received increased attention, and has been combined with principles of DNA‐origami to enable precise control over the spatial distribution and recruitment of proteins in adaptive scaffolds.…”

“…The assbembly of these units is again governed by an equilibrium constant (K eq ), which is simply a ratio of association (k a ) and disassociation (k d ) kinetics. Numerous supramolecular systems are capable of creating hydrogels including host/guest interactions, 69,70 directional hydrogen bonding, 71,72 peptide amphiphiles, [73][74][75] metal-ligand coordination, 76 and small molecule gelators. 77 In theory, such systems built on weak and non-covalent interactions are well situated to quickly respond to changes in the environment or secreted factors.…”

“…62 Numerous non-covalent and supramolecular hydrogels are capable of displaying viscoelastic behavior. 70,71,[152][153][154][155] However, there are no known studies linking this viscoelasticity to cellular behavior. Cellular adhesion to supramolecular surfaces 156,157 and supramolecular fibers 75 has been well demonstrated, yet the correlation to viscoelasticity or timescale remains to be reported.…”
