A Flexible Porous MOF Exhibiting Reversible Breathing Behavior through Single-Crystal to Single-Crystal Transformation

摘要

A two dimensional (2D) flexible Zn(II) MOF (1) with intra-layer channels has been synthesized using a mixed ligand strategy. Interestingly, 1 exhibits reversible breathing behavior upon desolvation/resolvation in crystal state, causing responsive luminescence together with visible color changes. Furthermore, the above-mentioned process even occurred when 1 exposed to humid atmosphere or immersed in various organic solvents.
