Supramolecular Polymers Explained While polymers are constructed from chemically bonded units, supramolecular polymers arise through reversible linkages, such as hydrogen bonding and electrostatic interactions. Recent advances in the field of supramolecular polymer science have moved from a fundamental understanding of assembly properties to the introduction of functionality, in order to exploit the particular features of this class of materials. Aida et al. (p. 813) review the specific features of supramolecular polymers that can lead to applications in a variety of fields, including: materials—in which processability and self-healing properties are of interest; biomedicine—in which the concerns are dynamic functionality and biodegradability; and hierarchical assembly and electronic systems—with an interest in unidirectionality of charge flow. Supramolecular polymers can be random and entangled coils with the mechanical properties of plastics and elastomers, but with great capacity for processability, recycling, and self-healing due to their reversible monomer-to-polymer transitions. At the other extreme, supramolecular polymers can be formed by self-assembly among designed subunits to yield shape-persistent and highly ordered filaments. The use of strong and directional interactions among molecular subunits can achieve not only rich dynamic behavior but also high degrees of internal order that are not known in ordinary polymers. They can resemble, for example, the ordered and dynamic one-dimensional supramolecular assemblies of the cell cytoskeleton and possess useful biological and electronic functions.
