Abstract

The slide-ring gel is composed of chemically cross-linked polyrotaxanes having poly(ethyleneglycol)(PEG) main chain and α-cyclodextrin(α-CD) rings. In this study, we prepared the slide-ring gels modified with azobenzene at α-CD by ether and isocyanate linkage. We evaluated aggregating behavior of azobenzene in the slide-ring gel and the effect of photoisomerization of azobenzene on the swelling properties of the gels.
