| Abstract: | A photocontrolled, interconvertible supramolecular 2D‐nanosheet/1D‐nanotube system was constructed through the supramolecular assembly of adamantanyl‐modified diphenylalanine with azobenzene‐bridged bis(β‐cyclodextrin). The nanosheet exhibited a greater fluorescence enhancement effect than the nanotube. Significantly, these nanosheets and nanotubes could interconvert via the photocontrolled trans/cis isomerization of azobenzene linkers in bis(β‐cyclodextrin), and this photo‐switchable one‐dimensional/two‐dimensional morphological interconversion was reversible and recyclable. This enables convenient routes to highly ordered nanostructures with various morphologies and dimensions that can be controlled by external stimuli. |
