| Research Abstract |
To create an innovative organic-inorganic hybrid materials in which the relative position of each component is variable, detailed structural analyses on the precursor polyrotaxane was carried out in solution. As a result, we revealed that the solventphilic cyclic components dispersed on the solventphobic axis polymer to cover thesolventphobic core with the solventphilic rings, like an amphiphilic random copolymer. In addition, we developed a versatile synthesis of polyrotaxane to clarify the effect of the end groups on the micelle formation and to simplify the synthesis. The synthetic breakthrough leaded to the finding of a novel viscoelastic relaxation of slide-ring materials. A systematic measurement of the relaxation on various slide-ring materials with different axis polymers revealed the dynamics of the sliding of partial chains through the cross-links. The observed dynamics corresponds to that of the variation of the relative position of each component of slide-ring materials. Furthermore, the detailed analysis of the equilibrium elasticity provided us a novel concept of the elasticity.
