Recognition of Polymer Side Chains by Cyclodextrins

	Enhancement of the Selectivity by the Steric Effect of Polymer Main Chain		Stimuli-Responsive Hydrogels
	Enhancement of the Selectivity by Multi-Site Interaction		Side Chain Polyrotaxanes with Unidirectional Inclusion
	Interaction of Cyclodextrins with Polymer Micelles

Stimuli-Responsive Hydrogels

Stimuli-responsive hydrogels are obtained from cyclodextrins, dodecyl-modified poly(sodium acrylate), and stimuli-responsive competitive guests.

Photoresponsive systems which exhibit contrasting viscosity changes are constructed from cyclodextrin-modified poly(sodium acrylate)s and azobenzene-modified poly(sodium acrylate)
