Top-down fabrication of crystalline metal–organic framework nanosheets

Abstract
Crystalline metal–organic framework (MOF) nanosheets have been fabricated via top-down delamination from bulk crystals of a layered MOF, {Zn(TPA)(H2O)·DMF}n (MOF-2), and characterized by Tyndall scattering, scanning electron microscopy and atomic force microscopy measurements. The delaminated MOF-2 nanosheets exhibit remarkable amine intercalation property and reversible amine exchangeability.
