Two-dimensional (2D) metal-organic frameworks (MOF) materials have recently gained much attention, for their interesting properties and potential applications in many fields, such as separation, catalysis and detector. To prepare 2D MOF materials, herein we present a bottom-up synthesis strategy, which relies on the diffusion mediated modulation or interfacial reaction. Scanning electron microscope (SEM) and atomic force microscope (AFM) analyses statement the micrometer lateral dimensions and nanometer thickness structures of these 2D MOF materials. Composites incorporating the 2D MOF materials within polymeric matrices were fabricated to a free-standing membrane, which exhibits outstanding gas separation. Optimized formulas of 2D MOF material and polymeric species and their ratios were design and investigated in detail.
