Control of halogen interactions on morphology of metal-organic framework nanosheets

Metal–organic framework nanosheets: from nano-scale to micron-scale with tunable color

“…In our group, the preparation of MONs with a single-layer limit, for functional adjustment and various applications, has been performed. [32][33][34][35][36][37][38] More recently, by quantitatively breaking the inter-layer halogen-bonding contacts through variations in ultrasonic duration and solvent polarity, for the same MONs, both the 2D nanosheets with lateral size larger than 500 nm and the one-dimensional (1D) nanoribbons with a lateral size smaller than 100 nm, can be obtained. 39 More importantly, the transformation from paramagnetic behavior to antiferromagnetic behavior, triggered by 3D-to-2D evolution, has been observed on MONs.…”
