Pseudopolyrotaxane composed of an azobenzene polymer and γ-cyclodextrin. Reversible and irreversible photoisomerization of the azobenzene groups in the polymer chain

Name: Work Video:
Duration: 3 min 30 s
Description: A polyrotaxane composed of γ-cyclodextrin and azobenzene containing polyester undergoes UV light induced isomerization of trans- to cis- azobenzene, whereas the reverse isomerization does not occur under the usual conditions of irradiation with visible light.
