A triply-responsive supramolecular vesicle fabricated by α-cyclodextrin based host-guest recognition and double dynamic covalent bonds.
The supramolecular construction of multi-stimuli assemblies is a challenging task for prospective use. In this work, a novel supramolecular amphiphile was fabricated by introducing molecules with dynamic covalent bonds into host-guest inclusion. The amphiphile formed a vesicle, which was characterized by transmission electron microscopy (TEM), dynamic light scattering (DLS), 1H NMR and UV-vis spectra. Furthermore, the vesicular structure could be regulated by pH, light and redox reagent, and thus the loaded dye in the vesicles could be released in a controlled manner.

Pyrene-appended alpha-cyclodextrin as a fluorescent pH probe responding to a wide range.
Pyrene-appended alpha-cyclodextrin (3) in which a trimethylenediamine linker connected the pyrene residue to the alpha-cyclodextrin moiety showed pH-dependent fluorescence intensity changes. The fluorescence intensity was almost linearly changed within the pH range of 5 - 10. The unique fluorescence response of 3 to the pH was due not only to the favorable pK(a) values (pK(a1) = 6.4 and pK(a2) = 8.8), but also to the almost equal contributions of the amino groups to the pyrene's fluorescence quenching.
