The application of hydrogen bonding recognition in designing and controlling over supramolecular polymers has attracted great attention recently due to the influence of hydrogen bonds on the thermodynamic properties, microscopic self-assembling, crystallizing and liquid crystallizing behaviors of such polymers. In this paper, the types and characters of hydrogen bonding systems, and the influences of molecular structures and intermolecular hydrogen bonds on the stability of hydrogen bonding systems are described systematically. The recent applications of hydrogen bonding recognition systems, including carboxylic acids and pyridine based system, nucleobase derived system and quadrupolar hydrogen bonding system, in supramolecular polymers are introduced. The synthetic methods, structures, properties and functions of hydrogen bonded supramolecular polymers are mainly addressed.
