Pyromellitate-bridged cyclodextrin nanosponges (CDNSs) evolved from sol into gel state upon gradual increase of the concentration from 0.2 to 2000 mg mL−1 in water. The enantiodifferentiating geometrical photoisomerizations of (Z)-cyclooctene and (Z, Z)-1,3-cyclooctadiene sensitized by CDNS at various concentrations were critically affected by the phase transition of CDNS to afford the corresponding (E)- and (E, Z)-isomers in the highest enantiomeric excesses in the gel state.
