Supramolecular glue: The photoinduced isomerization of difunctional azobenzenes can be used to induce and reverse the molecular recognition and adhesion of bilayer vesicles made up of cyclodextrin (CD) molecules. The molecular basis of this light-responsive supramolecular glue is the cistrans isomerization of the azobenzene (see picture; black circles CD, green trans-azobenzene, red cis-azobenzene).
