Two-dimensional (2D) MOFs nanosheets are prosperous regarding the novel peculiarity of nano-interface and broad development prospects, but the key to achieving the control and design of 2D nanomaterials' morphology is still arduous. In this work, we prepared two complexes contained pyrazine ligand, namely Ni(pyz) 2 Cl 2 and Ni(pyz) 2 Br 2 (pyz = pyrazine), which derived from a synthesis of bridged pyrazine and nickel halogen nide. 2D nanomaterials of them were obtained by using the liquid phase exfoliation method to feature a series of structure and surface morphology. We investigated the difference in physical and chemical properties between 2D MOFs nanomaterials and bulk materials, and studied the influence of different halogen interactions on the morphology of nanomaterials. The results showed that the stacking force and electronic transition have made a significant influence on the 2D nanomaterials. [Display omitted] • Ultra-thin 2D nanosheets of Ni-based MOFs have been prepared. • The correlation between halogen interactions and morphologies of 2D nanosheets has been proposed. • The influence of halogen interactions on the properties of 2D nanosheets has been demonstrated.
