“…Upon decomplexation via the addition of HEEDTA to selectively scavenge the Fe(II) or Zn(II) ions, the diblocks then showed similar LCST behavior as the starting terpyridine functionalized homopolymers, which hold great promise for the development of fully tuneable thermoresponsive metallo-supramolecular systems. [117] Further promising advances toward the future applications of metallo-polymers with thermoresponsive polymers include a recent report by Schubert and coworkers, [44] who showed the self-assembly of a novel metallosupramolecular triblock terpolymer; PS-block-poly( para-trifluoro- 70 linked by a bis-terpyridine ruthenium (II) complex. The amphiphilic metallo-supramolecular triblock copolymer self-assembled into various morphologies which were dependent upon the polarity of the solvent.…”

“…This is due to the upper critical solution temperature (UCST) of the PTFMS block in less polar solvents giving rise to an increased interfacial curvature of the amphiphile and hence a change in its preferred self-assembled morphology in solution ( Figure 18).

“…[27,29,36] This is perhaps owing to their ability to undergo conventional self-assembly into various morphologies, as for covalent block copolymers, yet still retain supramolecular reversibility and the unique properties of transition metal complexes, thus offering many advantages over conventionally synthesized architectures. [39][40][41][42][43][44] Moreover, in recent years, researchers have begun to pre-design and manipulate such metallo-supramolecular block copolymers to target specific nanostructures whereby a key design feature in their synthesis is utilized after self-assembly has occurred; viz, the supramolecular linkage can be selectively cleaved to remove the attached polymer blocks, thus producing novel functional architectures from tailor made parent self-assembled structures. [31,[45][46][47][48] In this feature article, we will provide a brief introduction to the field of main chain metallo-supramolecular block copolymers and evaluate recent literature on the topic of their specific design to undergo self-assembly to form tuneable and stimuli responsive higher order structures.…”

Many research groups have explored the properties and solution self-assembly of main chain metallo-supramolecular multiblock copolymers. Until recently, these metal complexes have been used to prepare mainly micelle type structures. However, the self-assembly of such copolymers has been exploited further to create more advanced architectures which utilize the reversible supramolecular linkage of their building blocks as a key component in their synthesis. Furthermore, the incorporation of multiple orthogonal interactions and stimuli responsive polymers into their design, enables more precise external control of their properties. This feature article discusses recent developments and provides an insight into their potential exploitation and development for the creation of novel, smart, and responsive nanostructures.

Synthetic Oral Mucin Mimic from Polymer Micelle Networks

Mucin networks are formed in the oral cavity by complexation of glycoproteins with other salivary proteins, yielding a hydrated lubricating barrier. The function of these networks is linked to their structural, chemical, and mechanical properties. Yet, as these properties are interdependent, it is difficult to tease out their relative importance. Here, we demonstrate the ability to recreate the fibrous like network through a series of complementary rinses of polymeric worm-like micelles, resulting in a 3-dimensional (3D) porous network that can be deposited layer-by-layer onto any surface. In this work, stability, structure, and microbial capture capabilities were evaluated as a function of network properties. It was found that network structure alone was sufficient for bacterial capture, even with networks composed of the adhesion-resistant polymer, poly(ethylene glycol). The synthetic networks provide an excellent, yet simple, means of independently characterizing mucin network properties (e.g., surface chemistry, stiffness, and pore size).

In this article, we first review supramolecular polymers from a conceptual point of view, describing the two extreme mechanisms, isodesmic or cooperative, which govern the supramolecular polymerization processes. We also review this topic from a more practical point of view, highlighting recent and remarkable examples of supramolecular polymers capable of forming highly organized structures or having interesting applications. Supramolecular polymers can exhibit the mechanical properties of plastics and elastomers, but possessing, at the same time, the ability to repair themselves due to the dynamic nature of the noncovalent interactions that join together the appropriate building blocks. The utilization of peptides, π‐electron‐rich substrates, or receptors for metals in the formation of the corresponding supramolecular polymers yields useful biological, electronic, or mechanical functions, respectively. The decoration of supramolecular polymers with stereogenic centers affords helical structures that can be utilized to investigate amplification of chirality that will shed light on the origin of homochirality. In short, supramolecular polymers integrate order and dynamics to achieve important functions such as response to stimuli, environmental adaptation, amplification of chirality, and self‐repair ability. This video details two pathways of supramolecular polymerization: isodesmic (top: monomer binding constant K does not vary with the degree of polymerization) and cooperative (bottom: the binding constant in the nucleation and elongation stages do not vary with the degree of polymerization, however, their values are different, K n ≠K e ). Supramolecular polymerizations can follow an isodesmic mechanism (top: monomer binding constant K does not vary with the degree of polymerization) or cooperative (bottom: the binding constant in the nucleation and elongation stages do not vary with the degree of polymerization, however their values are different, K n ≠K e ). media object Supramolecular polymerizations can follow an isodesmic mechanism (top: monomer binding constant K does not vary with the degree of polymerization) or cooperative (bottom: the binding constant in the nucleation and elongation stages do not vary with the degree of polymerization, however their values are different, K n ≠K e ).
