Think thin: Ultrathin chiral metal–organic framework (CMOF) nanosheets of only few layers in thickness are prepared for the first time by a biomimetic strategy. Benefiting from the much larger number of exposed chiral sites, ultrathin CMOF nanosheets exhibit far superior enantioselectivity in chiral separation than their bulk counterparts.
Abstract
Chiral metal–organic framework (CMOF) nanosheets only a few layers thick remain a virgin land waiting for exploration. Herein, the first examples of ultrathin CMOF nanosheets are prepared by the confinement growth of two-dimensional (2D) chiral layers, which are assembled by helical metal–organic chains within microemulsion. This convenient and easily scaled up inverse microemulsion method gives a series of 2D CMOF nanosheets composed of variable metal nodes or chiral ligands. More significantly, thanks to the exceptionally large number of chiral sites exposed on surfaces, the as-obtained CMOF nanosheets exhibit much higher enantioselectivity in chiral separation compared with their bulk counterparts.
