Abstract:
A compound comprising crosslinked polyrotaxane, wherein the crosslinked polyrotaxane has a first and a second polyrotaxane, the first polyrotaxane having a first linear molecule and a first cyclic molecule, the first linear molecule having the first cyclic molecule included in a skewered manner which allows the first linear molecule to pass through the opening of the first cyclic molecule, and having at each end a first blocking group which is placed so as to prevent the elimination of the first cyclic molecule, the second polyrotaxane having a second linear molecule and a second cyclic molecule, the second linear molecule having the second cyclic molecule included in a skewered manner which allows the second linear molecule to pass through the opening of the second cyclic molecule, and having at each end a second blocking group which is placed so as to prevent the elimination of the second cyclic molecules, each opening of the first and second cyclic molecules is substantially cylic, and the crosslinked polyrotaxane is formed by linking at least one of the first cyclic molecules and at least one of the second cyclic molecules via chemical bonding.
