Ultrathin Chiral Metal-Organic Frameworks Nanosheets for Efficient Enantioselective Separation.

In this report, the first example of ultrathin CMOFs nanosheets is successfully fabricated via the confinement growth of two-dimensional (2D) chiral layers, which are assembled by helical metal-organic chains within microemulsion. Impressively, this convenient and easily scaled up inverse microemulsion protocol is capable of fabricating a series of 2D CMOFs nanosheets composed of variable metal node or alternative chiral ligand. More significantly, thanks to the exceptionally large number of chiral sites exposed on surfaces, as-obtained CMOFs nanosheets exhibit much higher enantioselectivity in chiral separation compared with the bulk counterparts. Evidently, the generality of developed preparation strategy as well as the superior performance of ultrathin CMOFs nanosheets not only expand the members of 2D materials library but also offer the opportunity to conquer the grand challenges in chirality-associated applications.
