| 英文摘要 | Three kinds of photoresponsive copolymers with azobenzene side chains were synthesized by radical polymerization of n-4-phenylazophenylacrylamide (papa) with n-isopropylacrylamide (nipam), n,n-diethylacrylamide (deam) or n,n-dimethylacrylamide (dmam) respectively. their structures were characterized by ft-ir, h-1-nmr and uv/vis spectroscopy. their reversible photoresponses were studied with or without alpha-cyclodextrin (alpha-cd), which showed that both the copolymers and their inclusion complexes with alpha-cd underwent rapid photoisomerization. the lower critical solution temperature (lcst) of the copolymers and their inclusion complexes with alpha-cd were investigated by cloud point measurement, which showed that the lcst of three kinds of copolymers increased largely after adding alpha-cd. after uv irradiation on the solutions of copolymers and their inclusion complexes, the lcst of the copolymers increased slightly with the absence of alpha-cd, while decreased largely with the presence of alpha-cd. furthermore, the lcst reverted to its originality after visible light irradiation. this change of lcst could be reversibly controlled by uv and visible light irradiation alternately. in particular, in the copolymer of papa and dmam, the reversible water solubility of the inclusion complexes could be triggered by alternating uv and visible light irradiation. |
