Abstract

The isolation of 2D-materials is already a success for graphene, graphene oxide, boron nitride and a fewclays or metal chalcogenides, however despite the fact that some of them show very interesting physicalproperties, they lack useful functionalities. Metal–Organic Frameworks (MOFs) are multifunctionalmaterials showing a wide range of physical and chemical properties that can be structurally designed bysuitable selection of their building-blocks. This strategy may allow the production of layers with a varietyof useful electronic and molecular recognition functionalities. Herein we isolate 2D-MOF flakes withareas of hundreds of square microns and an excellent control of the molecular thickness (from single upto ca. 50 layers). The samples exhibit such good photoluminescence and mechanical properties as toallow free-standing characterization of few layers’ flakes.
