On July 22, 2020, Cui, Peng; Svensson Grape, Erik; Spackman, Peter R.; Wu, Yue; Clowes, Rob; Day, Graeme M.; Inge, A. Ken; Little, Marc A.; Cooper, Andrew I. published an article.Reference of 1,2-Dimethoxybenzene The title of the article was An Expandable Hydrogen-Bonded Organic Framework Characterized by Three-Dimensional Electron Diffraction. And the article contained the following:
A mol. crystal of a 2-D hydrogen-bonded organic framework (HOF) undergoes an unusual structural transformation after solvent removal from the crystal pores during activation. The conformationally flexible host mol., ABTPA, adapts its mol. conformation during activation to initiate a framework expansion. The microcrystalline activated phase was characterized by three-dimensional electron diffraction (3D ED), which revealed that ABTPA uses out-of-plane anthracene units as adaptive structural anchors. These units change orientation to generate an expanded, lower d. framework material in the activated structure. The porous HOF, ABTPA-2, has robust dynamic porosity (SABET = 1183 m2 g-1) and exhibits neg. area thermal expansion. We use crystal structure prediction (CSP) to understand the underlying energetics behind the structural transformation and discuss the challenges facing CSP for such flexible mols. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Reference of 1,2-Dimethoxybenzene
