Metal-organic framework (MOF) materials, a new type of inorganic-organic hybrid materials, are self-assembled from organic ligands and metal ions/cluster centres through coordination. MOFs with unique pore structures have shown great potential for metal ions luminescent sensing.
Since the discovery of graphene, Since the discovery of graphene, series of two-dimensional (2-D) nanosheets materials such as metal oxides, metal hydroxides, transition metal chalcogenides (TMDs), boron nitride (BN) and black phosphorus have been of great interests, and have been extensively investigated for applications in electronics, lithium-ion batteries, catalysis and mechanical properties, etc.
2-D MOF nanosheets materials, as a new member of the 2-D nanomaterials family, are still at the very early stage. However, to the best of our knowledge, the 2-D MOF nanosheets materials for luminescent sensing have been rarely explored.
