Solid-State Reshaping of Crystals:Flash Increase in Porosity of Zirconium Phosphate-Hypophosphite That Contains Polyethylenoxa Diphosphonate Pillars

摘要

Engineering of crystals and solids is an active area of research that intertwines the concepts of supramolecular chemistry and materials science.The supramolecular construction of nanoporous solids with ample,open voids that can be freely accessed by other molecular species is quite a difficult task and pursued by a vast number of research groups.One common approach is the spontaneous aggregation of dissolved small-molecular building blocks.However,its success is rather limited because for the self-aggregation to render useful architectures,one should posses a profound predictive knowledge of the involved intermolecular forces,which implies the proposition and preparation of molecules("aggregons")with suitable geometries and functionalities.Yet,worse,once the crystal or solid is formed,there are few opportunities,if any,to further manipulate its structure.
