Metal-Organic Frameworks: Synthesis and Applications

The isolation of nanostructures consisting of 10–25 layers of a covalent organic framework is confirmed by AFM carried out on several surfaces. This is achieved by means of selective ultrasound exfoliation on the bulk layered material. TEM demonstrates the porous nature of the free-standing layers on a carbon gird. The chemical composition of this novel 2D polymer is determined by infrared, X-ray photoelectron, and electron-energy-loss spectroscopy.
