The past few decades have seen a significant growth in the field of supramolecular
polymerizations,in which(reversible)noncovalent interactions(e.g.,hydrogen bonding,metal-ligand
coordination,π-πstacking,etc.)between(macro)monomeric units are utilized to build polymeric assem-
blies.These polymeric aggregates can exist in an equilibrium state between low and high molecular weight
species,which in turn opens the door to a new matrix of properties.For example,such supramolecular
polymers are potentially an interesting class of stimuli-or environmentally responsive,“smart”materials.
Additionally,the establishment of an equilibrium during the assembly process imparts on the system the
ability to“proofread”assemblies and,depending on the nature of the(macro)molecules,can allow efficient
access to controlled,well-defined nanostructures.This Perspective will focus on the basic concepts of
such supramolecular polymerizations,such as mechanism of assembly growth,and the effects of growth
kinetics,phase segregation,and growth on the surface has on the assembly and properties of the resulting
supramolecular polymers,highlighting these concepts with selected literature examples.
