Photo-controlled molecular recognition of alpha-cyclodextrin with azobenzene containing polydiacetylene vesicles

Herein, photo-controlled inclusion and exclusion reaction of azobenzene-containing polydiacetylene vesicles with alpha-cyclodextrin were used to act as driving force to induce chromatic transition of PDA vesicles, which provided a novel model system that combines photochemistry and host-guest chemistry for a photo-stimulus-responsive vesicle.
