Description
Summary:An all‐inorganic soft framework is rare but interesting for both fundamental research and practical applications. Here, an all‐inorganic soft framework based on a transition metal oxide is reported. The periodic connection of a one‐dimensional anionic tungstoselenate molecular wire building block with a CoII ion is used to construct the crystalline material. The crystal structure of the material was determined by high‐angle annular dark‐field scanning transmission electron microscopy combined with several characterization techniques. The soft framework of the material enables water adsorption/desorption with a change in its structure, leading to a high level of water adsorption. The framework of the material is flexible, and the structure of the molecular wire building block is stable during the water adsorption/desorption process. Flexible framework: An all‐inorganic porous soft framework based on transition metal oxide was synthesized and characterized. The flexible structure changed reversibly with a water adsorption/desorption process.
