Two-dimensional (2-D) materials, which show excellent physical and chemical properties, have received unprecedented attention and become a research hotspot in scientific fields such as physics, chemistry and materials. Organic modification onto 2-D materials by covalently bonding or physically adsorbing organic molecules can greatly regulate and optimize the properties of 2-D materials. However, the organic modification methods reported so far are exfoliation first and then an organic modification (E-M) strategy, which usually possess some disadvantages such as less modification ratio, uncertain type, number and position of the functional groups, a tendency for defects and so on. Therefore, the development of functionalization of 2-D materials is greatly limited.
