Abstract:
1. A material comprising a first polyrotaxane and a second polyrotaxane, wherein the first polyrotaxane comprises a first cyclic molecule(s), a first linear molecule which is included in a cavity or cavities of the first cyclic molecule(s) in a skewered manner, and a first capping group which is located at each end of the first linear molecule to prevent the dissociation of the first cyclic molecule(s), wherein the second polyrotaxane comprises a second cyclic molecule(s), a second linear molecule which is included in a cavity or cavities of the second cyclic molecule(s) in a skewered manner, and a second capping group which is located at each end of the second linear molecule to prevent the dissociation of the second cyclic molecule(s), wherein a part of the first polyrotaxane and the second polyrotaxane is bound to each other through the first cyclic molecule(s) or through the first or second cyclic molecule(s), wherein the first cyclic molecule(s) and the second cyclic molecule(s) each has a photo-reactive group that is not a photosensitive group, wherein each of the photo-reactive groups in the first and second cyclic molecules is a group having an unsaturated bond, and wherein the first and second polyrotaxanes are bound to each other by a photo-crosslinking reaction between the photo-reactive groups, wherein a reaction initiator is used in the photo-crosslinking reaction.
