• The glassy state of a two‐dimensional (2D) Cd2+ coordination polymer crystal was prepared by a solvent‐free mechanical milling process. The glassy state retains the 2D structure of the crystalline material, albeit with significant distortion, as characterized by synchrotron X‐ray analyses and solid‐state multinuclear NMR spectroscopy. It transforms to its original crystal structure upon heating. Thus, reversible crystal‐to‐glass transformation is possible using our new processes. The glass state displays superior properties compared to the crystalline state; specifically, it shows anhydrous proton conductivity and a dielectric constant two orders of magnitude greater than the crystalline material. It also shows material flexibility and transparency. Phase transitions: The glassy state of a two‐dimensional (2D) Cd2+ coordination polymer crystal was prepared by a solvent‐free mechanical milling process. The coordination polymer shows an increased proton conductivity and an increased dielectric constant in the glassy state (see picture).
