Contrast Viscosity Changes upon Photoirradiation for Mixtures of Poly(acrylic acid)-Based alpha-Cyclodextrin and Azobenzene Polymers

摘要

Stimuli-responsive self-assembling systems have attracted much interest from researchers because of their potentials in a broad range of fields,such as drug delivery systems,sensor systems,and functional nanodevices.Cyclodextrins(CDs)are a promising material for construction of stimuli-responsive self-assembling systems.Recently,in the course of our study of molecular recognition of CDs with polymer side chains,we have successfully constructed a photoresponsive hydrogel system using molecular recognition by combination of alpha-CD,dodecyl-modified poly(acrylic acid),and a photoresponsive competitive guest.
