This review describes (1) the precise synthesis of polyrotaxane (PRx) and (2) materials using PRx. PRx has a necklace-like structure in which a linear molecule penetrates the cavity of a cyclic molecule and both ends of the linear molecule are capped with a bulky substituent. The supramolecular structure of PRx can be formed with cyclic molecules used as building blocks. PRx exhibits many features (e.g., cyclic molecule slippage) that are not found in other supramolecular structures. In this review, we report that the number of cyclic molecules, the length (molecular weight) of the linear molecules, and the combination of the cyclic molecules and linear molecules in PRx can be precisely controlled to maximize cyclic molecule slippage. In addition, we created a material that quickly recovers its material strength because of the cyclic molecule slippage of PRx.
