| 英文摘要 | Photoresponsive polymer with azobenzene pendant group (pdmaa-co-papa) was synthesized by radical polymerization of nn-dimethylacrylamide (dmaa) and n-4-phenylazophenyl acrylamide (papa), and the characterization of the inclusion complexes of the pdmaa-co-papa with alpha-cyclodextrin (alpha-cd) were performed by ftir, gpc, h-1 nmr, 2d noesy, and uv-vis spectroscopy. it was found that the solubility of pdmaa-co-papa and alpha-cd inclusion complexes in aqueous solution showed tunable property, which could be triggered by alternating uv-vis light irradiation at a certain temperature due to the effect of molecular recognition of alpha-cd with azobenzene moiety in the polymer. after uv irradiation, the lower critical solution temperature (lcst) of the polymer aqueous solution increased slightly without (alpha-cd while the lcst decreased sharply at presence of alpha-cd. furthermore, uv spectroscopy showed that the photoisomerization of the polymer solution went on rapidly and reversibly, and 2d noesy data suggested that the inclusion complexation of alpha-cd with trans azobenzene moiety and the decomplexation with cis azobenzene resulted in reversible solubility behavior when objected to uv and vis light irradiation alternately.
