Supramolecular polymer is a new interdiscipline of supramolecular chemistry and polymer science. In supramolecularly polymeric structures the monomers are connected by noncovalent bonds such as hydrogen bonds, metal-organic coordinations, and host-guest interactions and so on. Supramolecular polymers constructed on the basis of host-guest interactions constitute of a main branch of the whole family of supramolecular polymers. In this review, some representative progress on the construction of supramolecular polymers based on host-guest interactions has been summarized, after a brief introduction of the concept and history of supramolecular polymer. It has been divided into five parts according to the different structures of the host molecules. In the last part, the challenges and prospective tendency of this subject have also been discussed.
