Reversible shape memory two-dimensional covalent organic frameworks.

ABSTRACT: Two-dimensional covalent organic frameworks are a unique type of organic crystals with both weak layer-layer interaction and regular one-dimensional nanochannels. Therefore, it is possible to synthesize two-dimensional covalent organic frameworks with reversible stacking phases and thus pore sizes, which hold great potential applications in future nanoelectronics, nanoreactors, intelligent response, gas separation and storage. However, such a goal remains challenging up to now, because the slipped AA-stacking is the most thermodynamically stable phase. Here, we report the realization of shape memory two-dimensional covalent organic frameworks with reversible interlayer stacking sequences, of which AA and inclined phases are induced by the formation of hot ice and the strongly adsorbed orga
