Supramolecular polymers are formed of monomeric units via reversible non-covalent bonds

including hydrogen bonds

π-π interactions

metal ligand binding and so on.Owing to the directionality and strength of the supramolecular bonding

such polymers exhibit many useful functional properties

such as stimuli-responsiveness and self-assembly of nanostructures.This paper described the advances of multiple hydrogen bonding supramolecular polymers in modifying polymer properties

self-assembling molecular architectures

self-assembling nanostructures and so on during the past three years.The application of such polymers was mentioned as well.
