Hydrogen-bonding supramolecular polymers

Hydrogen bonds are widely used in the construction and performance improvement of supramolecular polymers due to their several advantages, such as directivity, strong binding force, dynamic reversibility and predictable recognition performance. In this paper, the recent developments of main-chain type, side-chain type and combined type hydrogen bonded supramolecular polymers are summarized in detail according to the number of hydrogen bonding sites. More emphatically, the design of various hydrogen bonded units and the functions of them in improving the properties of polymers are elaborated. At the same time, the applications of hydrogen bonded units in the fields of nano material, gels, liquid crystals, and so on, are introduced. Based on this, the research directions of hydrogen-bonded supramolecular polymers in the future are prospected, including the design and synthesis of stable multiple hydrogen-bonded units under physiological conditions and the further study of assembly mechanism.
