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.

可调谐的超分子组装和基于环糊精/二苯丙氨酸的1D和2D纳米结构的光开关转换。

通过金刚烷基修饰的二苯丙氨酸与偶氮苯桥联的双（β-环糊精）的超分子组装，构建了一个光控，可互变的超分子2D纳米片/ 1D纳米管系统。纳米片表现出比纳米管更大的荧光增强效果。值得注意的是，这些纳米片和纳米管可以通过双（β-环糊精）中偶氮苯连接基的光控反式/顺式异构化进行互变，并且这种可光转换的一维/二维形态学互变是可逆的且可回收的。这使得可以方便地路由到可以通过外部刺激控制的具有各种形态和尺寸的高度有序的纳米结构。
