Research Abstract |
We chemically modified cyclodextrins as sliding host molecules on the sparse polyrotaxane. By chemically cross-linking the modified polyrotaxane in the solution, we realized new sliding gels named "sliding-host gel", and estimated the inclusion properties of the sliding-host. Then, we realized active transportation of guest molecules using exchange of two kinds of guests in sliding-host gel. We found reversible gelation of polyrotaxane with sliding hosts and sliding guests by photoisomerization of the guest molecules.
